The following safety precautions should be observed before using this product and any associated instrumentation.
Although some instruments and accessories would normally be used with non-hazardous voltages, there are situations
where hazardous conditions may be present.

This product is intended for use by qualified personnel who recognize shock hazards and are familiar with the safety
precautions required to avoid possible injury. Read and follow all installation, operation, and maintenance information
carefully before using the product. Refer to the manual for complete product specifications.

If the product is used in a manner not specified, the protection provided by the product may be impaired.

The types of product users are:

Responsible body

trained.

Operators

Service personnel

properly trained service personnel may perform installation and service procedures.

Keithley products are designed for use with electrical signals that are rated Installation Category I and Installation
Category II, as described in the International Electrotechnical Commission (IEC) Standard IEC 60664. Most mea­surement, control, and data I/O signals are Installation Category I and must not be directly connected to mains voltage
or to voltage sources with high transient over-voltages. Installation Category II connections require protection for high
transient over-voltages often associated with local AC mains connections. Assume all measurement, control, and data
I/O connections are for connection to Category I sources unless otherwise marked or described in the Manual.

Exercise extreme caution when a shock hazard is present. Lethal voltage may be present on cable connector jacks or
test fixtures. The American National Standards Institute (ANSI) states that a shock hazard exists when voltage levels
greater than 30V RMS, 42.4V peak, or 60VDC are present.

age is present in any unknown circuit before measuring.

Operators of this product must be protected from electric shock at all times. The responsible body must ensure that
operators are prevented access and/or insulated from every connection point. In some cases, connections must be ex­posed to potential human contact. Product operators in these circumstances must be trained to protect themselves from
the risk of electric shock. If the circuit is capable of operating at or above 1000 volts,

may be exposed.

Do not connect switching cards directly to unlimited power circuits. They are intended to be used with impedance
limited sources. NEVER connect switching cards directly to AC mains. When connecting sources to switching cards,
install protective devices to limit fault current and voltage to the card.

Before operating an instrument, make sure the line cord is connected to a properly grounded power receptacle. Inspect
the connecting cables, test leads, and jumpers for possible wear, cracks, or breaks before each use.

When installing equipment where access to the main power cord is restricted, such as rack mounting, a separate main
input power disconnect device must be provided, in close proximity to the equipment and within easy reach of the
operator.

For maximum safety, do not touch the product, test cables, or any other instruments while power is applied to the cir­cuit under test. ALWAYS remove power from the entire test system and discharge any capacitors before: connecting
or disconnecting cables or jumpers, installing or removing switching cards, or making internal changes, such as in­stalling or removing jumpers.

Do not touch any object that could provide a current path to the common side of the circuit under test or power line (earth)
ground. Always make measurements with dry hands while standing on a dry, insulated surface capable of withstanding the
voltage being measured.

The instrument and accessories must be used in accordance with its specifications and operating instructions or the
safety of the equipment may be impaired.

Do not exceed the maximum signal levels of the instruments and accessories, as defined in the specifications and op­erating information, and as shown on the instrument or test fixture panels, or switching card.

When fuses are used in a product, replace with same type and rating for continued protection against fire hazard.

Chassis connections must only be used as shield connections for measuring circuits, NOT as safety earth ground con­nections.

If you are using a test fixture, keep the lid closed while power is applied to the device under test. Safe operation re­quires the use of a lid interlock.

If or is present, connect it to safety earth ground using the wire recommended in the user documentation.

The symbol on an instrument indicates that the user should refer to the operating instructions located in the manual.

The symbol on an instrument shows that it can source or measure 1000 volts or more, including the combined
effect of normal and common mode voltages. Use standard safety precautions to avoid personal contact with these
voltages.

Instrumentation and accessories shall not be connected to humans.

Before performing any maintenance, disconnect the line cord and all test cables.

To maintain protection from electric shock and fire, replacement components in mains circuits, including the power
transformer, test leads, and input jacks, must be purchased from Keithley Instruments. Standard fuses, with applicable
national safety approvals, may be used if the rating and type are the same. Other components that are not safety related
may be purchased from other suppliers as long as they are equivalent to the original component. (Note that selected parts
should be purchased only through Keithley Instruments to maintain accuracy and functionality of the product.) If you
are unsure about the applicability of a replacement component, call a Keithley Instruments office for information.

To clean an instrument, use a damp cloth or mild, water based cleaner. Clean the exterior of the instrument only. Do
not apply cleaner directly to the instrument or allow liquids to enter or spill on the instrument. Products that consist
of a circuit board with no case or chassis (e.g., data acquisition board for installation into a computer) should never
require cleaning if handled according to instructions. If the board becomes contaminated and operation is affected,
the board should be returned to the factory for proper cleaning/servicing.

Am9513A System Timing Controller

All data transfers to an Am9513A system timing controller unit use two
I/O ports. Data transfer, such as loading and reading counters and counter
mode registers, uses the port at the specified base address.

The port at Base Address +1h carries addressing, command, control, and
status information. The many internal registers of the Am9513A require
an indirect system of access using a Data Pointer register, which is
accessed through the Command register. The Command register also
performs other functions such as loading and enabling the counters,
latching counter contents, and so on. For more information on base
addresses and how to set them, see Section 6.

Note:

Appendix C.

Digital I/O Ports

The CTM-10 board has four 8-bit digital I/O ports with latches while the
CTM-05/A board has two 8-bit digital I/O ports with latches. Latches are
electronic gates that hold data in position for a specific operation and
duration.

The digital I/O ports are totally independent of the Am9513A
counter/timer circuitry. You can use these I/O ports for any purpose
regardless of the counter’s operation.

The port A input (at Base Address +2h) provides eight digital input lines
(AIN0 to AIN7) for both the CTM-05/A and CTM-10. On the CTM-10,
the port B input (at Base Address +6h) provides eight additional digital
input lines (BIN0 to BIN7). The LSTTL-compatible (low-power Schottky
transistor-transistor logic) input ports use a transparent 8-bit latch
(74LS373); while the Strobe line is high, data passes through the latch.
Data present when the Strobe line is taken low is latched and held as long
as the Strobe line remains low.

For detailed information on programming the Am9513A, refer to

2-4 Functional Description

The gate signal for the latches is available at the digital input

Note:

connector (AENB, BENB).

The port A output (at Base Address +3h) provides eight digital output
lines for both the CTM-05/A and the CTM-10. On the CTM-10, the port
B output (at Base Address +7h) provides an additional eight digital output
lines. On the CTM-10, the four least significant bits of the port A input
(AIN0 to AIN3) and port A output (AOUT0 to AOUT3) are wired to the
50-pin main I/O connector; the four most significant bits of the port A
input (AIN4 to AIN7) and port A output (AOUT4 to AOUT7) are wired to
the 37-pin auxiliary connector. Also on the CTM-10, all eight bits of the
port B input (BIN0 to BIN7) and port B output (BOUT0 to BOUT7) are
wired to the 37-pin auxiliary connector. Refer to Appendix B for the pin
assignments of these connectors.

Each digital output can sink up to 8 mA and drive five standard TTL
(transistor-transistor logic) loads or 20 low-power Schottky TTL loads.
For more information on base addresses and how to set them, see
Section 6.

Programmable Interrupt Logic

The programmable interrupt logic contains a flip-flop that sets on a rising
edge (0 to 1 transition) of the selected interrupt source. The interrupt
source is software-selectable and can be set to any one of the five
Am9513A counter outputs or to an external interrupt input. The CTM-10
contains independent interrupt logic for Am9513A units A and B.

The state of the interrupt flip-flop can be determined by reading the unit A
Interrupt Status register at Base Address +3h (for the CTM-05/A or
CTM-10) or the unit B Interrupt Status register at Base Address +7h (for
the CTM-10 only). Reading these registers automatically resets the
interrupt flip-flop and interrupt request signal, if they are set.

In applications that “poll” the state of the interrupt request bit (as opposed
to responding to a hardware interrupt request), software must execute a
redundant read of the Status register whenever an interrupt request is set.

Programmable Interrupt Logic 2-5

This read is necessary to ensure proper resetting of the interrupt request
bit.

The interrupt flip-flop can be set to initiate an interrupt on levels 3, 5, 7,
10, 11, or 15 of the host computer. Selection of an interrupt source, level,
and enable/disable is made through the unit A Interrupt Control register at
Base Address 2h (for the CTM-05/A and CTM-10) or through the unit B
Interrupt Control register at Base Address +6h (for the CTM-10 only).

For compatibility with existing CTM-05 applications, unit A of the
CTM-05/A and CTM-10 provides jumper-selectable interrupts. This
feature allows a signal applied to the external interrupt input to drive the
interrupt-request signal selected by a 7-position jumper (for levels 2 to 7
plus a

disable

signal in this mode; when AENB

position). The AENB

is driven to logic 0, the signal applied to

external input functions as an enable

AINT drives the corresponding interrupt input (AINT = 1 drives the
interrupt active when AENB

= 0). Note that when any of the
software-selectable interrupt levels is selected, the jumper-selected
interrupt feature is disabled.

Unpacking and Inspecting a Board 3-1

Your computer must be turned off and grounded before

must not be removed until you have discharged any static electricity
by either of the following methods:

– If you are equipped with a wrist grounding strap, you discharge

static electricity as soon as you hold the wrapped board.

– If you are not equipped with a wrist grounding strap, you can

discharge static electricity by holding the wrapped board in one
hand while placing your other hand firmly on a metal portion of
the computer chassis.

2. Carefully unwrap the board from its anti-static wrapping material.

(Store the wrapping material for future use.)

3. Inspect the board for signs of damage. If any damage is apparent,

return the board to the factory; refer to Section 8 for more
information.

4. Check the contents of your package against its packing list to be sure

the order is complete. Report any missing items to the factory
immediately.

When you have determined that the board is acceptable, you can
configure the board, as described in the following section.

To use a CTM-10 or CTM-05/A board, you need to set a base address and
interrupt level (if interrupts are used) unique to each board in your
system. Use switch S1 to set the base address, and use jumper block J3 to
set the interrupt level.

Figure 3-1 shows the physical layout of the CTM-10 board, and Figure
3-2 shows the physical layout of the CTM-05/A board. These diagrams
show the locations of switch S1 and jumper block J3. Refer to

Note:

refer to Section 4.

Setting the Base Address

The default base address settings in the DriverLINX configuration

Note:

file is 300h for board 0. Make sure the switch settings for each board
match the settings in the DriverLINX configuration file.

The base address switch block contains seven switches, labeled 1 through

7. Switch 1 corresponds to the Most Significant Bit (MSB) of the base
address; switch 7 corresponds to the LSB of the base address. You place a
switch in the ON position (logic 0) by sliding the switch toward the top
(numbered side) of the switch block. You place a switch in the OFF
position (logic 1) by sliding the switch toward the bottom (unnumbered
side) of the switch block. Figures 3-3 and 3-4 illustrate the setting for a
base address of 300h (786 decimal); switches 1 and 2 are in the OFF
position and switches 3, 4, 5, 6, and 7 are in the ON position.

board a new base address. Base addresses for the CTM-10 are set on
8-byte boundaries that range from 100h to 3F8h. Refer to the I/O address
space mapping in your computer’s documentation to determine available
addresses.

3-10 Setup and Installation

Setting the Board Interrupt Level

On both a CTM-10 and CTM-05/A, you normally set the interrupt-level
jumper to position X on jumper block J3 (as shown in Figure 3-5) and use
software to select an interrupt level. Using software, you can select from
interrupt levels 3, 5, 7, 10, 11, and 15, while the jumper is at the X
position.

2

Figure 3-5. Normal Interrupt-Level Setting for the CTM-10 and

With the jumper at position X, no interrupt level is selected at power-up;
you must, therefore, write your application program to make the
selection. You can then program the CTM-10 and CTM-05/A boards to
generate interrupts in response to the selected interrupt level. Note that
the CTM-10 has separate, independent interrupt logic for units A and B.

Jumper Block J3

34567 X

Jumper Set to X
(disable) Position

CTM-05/A

You use jumper block J3 to select an interrupt level from levels 2 to 7 only
when you want your CTM-10 or CTM-05/A to be backward-compatible
with an existing CTM-05 application. You must use the jumper-select
feature in conjunction with the external interrupt input/interrupt enable,
as described in

Programmable Interrupt Logic

on page 2-5. On the

CTM-10, only unit A supports jumper selection.

If you use the jumper-select feature, avoid using a level already in use by
another device.

When using the jumper-select feature, you can enable the tristate driver
that drives the jumper-selected interrupt line by taking the Interrupt
Enable signal (pin 2 of the auxiliary connector on the CTM-10; pin 2 on

Configuring a Board 3-11

the CTM-05/A) to a logic-0 level. The output of this driver drives the
interrupt request line selected by the jumper.

A logic 1 on the Interrupt Input signal (pin 1 of the auxiliary connector on
the CTM-10; pin 1 on the CTM-05/A) generates an interrupt after the
8259 Interrupt Controller is enabled.

Installing the Board

Caution:

Installing the Board 3-13

Using the DriverLINX Configuration Panel

After you have successfully installed the CTM-10 and CTM-05/A
board(s) in your computer, start Windows to install DriverLINX. For
detailed instructions on installing DriverLINX, see the documentation
provided on the DriverLINX CD-ROM; especially the

Installation and Configuration Guide
Programming Guide

To configure a CTM-10 or CTM-05/A board (logical device), use the
DriverLINX icon in the Windows Control Panel application. The

Note:

require that users installing or configuring device drivers log on under an
administrative account.

Use the Configuration Panel to tell DriverLINX the model of the board
you’ve installed, its base I/O address, and the interrupt channel you’ve
assigned to the board, if it has one. You can also instruct DriverLINX to
initialize the hardware into a custom configuration of input and output
ports and default output values. This may be useful if you connect your
hardware’s outputs to external devices that expect high logic signals,
rather than the default low logic signals, as their starting state.

Pushing the Setup button on the DriverLINX Configuration Panel

2. At this point, you may select OK and accept default initialization,

select the Special Properties dialog, or select another Property Page.

3. If you select the Special Properties Dialog, you may configure

features unique to the installed hardware board:

●

Frequency Scaler —

this switches the frequency divider for the
master oscillator prescaler between binary and Binary Coded
Decimal (BCD) counting modes.

●

FOUT — this specifies the clock source, prescaler value, and
output (gate) option for the AM9513’s FOUT line.

Note: DriverLINX uses the same values for all AM9513 chips on the

counter/timer. To set different characteristics for each AM9513 on the
CTM-10 board, configure the hardware as two individual Logical
Devices.

4. If you select the Counter/Timer Property page, you may select the
master internal clock frequency that the hardware inputs to the
prescaler for the counter/timer channels and to define the interrupt
channel, if any, for the counter/timers. Enter selections for the
following fields:

● Resolution — specifies the master internal clock frequency that

the counter/timers use.

● Interrupt — specifies the interrupt channel you have assigned to

your hardware. If you are not using interrupts, select “none.”

Using the DriverLINX Configuration Panel 3-15

5. If you select the Digital Input Property page, you may assign an
interrupt channel to your board, if it supports interrupts for digital
input, and to modify DriverLINX’s default hardware initialization.
DriverLINX disables options not supported by your hardware. Enter
the selections for the following fields:

● Channels — shows the available Logical Channels for digital

input and selects the Logical Channel for the Configuration
properties.

● Interrupt — specifies the interrupt channel you have assigned to

your hardware. If you are not using interrupts, select “none.”

● DMA level — specifies the DMA channel you have assigned to

your hardware. Most counter/timer boards do not use DMA.

Note: DriverLINX disables the Configuration group if the board’s digital

channels do not support software reprogramming as inputs or outputs.

6. If you select the Digital Output Property page, you may define output
values for initializing the ports. You are allowed to define interrupt
resources if you did not define them on the Digital Input Property
Page. By default, DriverLINX sets output values to zero. To change
the defaults, modify the following fields:

● Channels — shows the available Logical Channels for digital

output and selects the Logical Channel for the Initialization
properties.

● Value — specifies the output value DriverLINX uses to initialize

the port selected in the Channels list box. DriverLINX ignores
this property if Initialize is not checked.

● Initialize — when checked, this property indicates that

DriverLINX should automatically initialize this channel as
specified in the Value property.

3-16 Setup and Installation

7. To Statistically Initialize Digital Output Ports (initialize Logical
Channel 0 with all bits at logic high), on the Digital Output Property
page:

● Select “0 (bits 0 - 7)” in the Channels list box.

● Enter “255” (DEC) or “0xFF:” (Hex) in the Initialization Value

edit box.

● Click the Initialize check box.

● Repeat this procedure for every Logical Channel that requires

user-defined initialization.

8. After completing all Property Pages, press OK to save your
configuration.

For programming your counter/timers with DriverLINX, refer to
DriverLINX Counter/Timer Programming Guide on the DriverLINX
CD-ROM.

You can use DriverLINX to verify board operation.

1. To physically initialize the CTM-10 or CTM-05/A, select
Device/Initialize from the main menu in Learn DriverLINX.

2. The first time the CTM-10 or CTM-05/A is initialized, or after a
configuration change, DriverLINX runs a diagnostic program to
verify the operation and accuracy of the configuration settings.

You are now ready to make I/O connections. Refer to Section 4 for
descriptions of common I/O accessories and connections for CTM-10 and
CTM-05/A boards.

FREQ determines the output frequency of the Dual Frequency Time

●

Base select (directed to unit A at Base Address +2h only on both the
CTM-10 and the CTM-05/A), as follows:

– 0 = 1 MHz (power-up default)

– 1 = 5 MHz

Note:

While the FREQ bit of the Interrupt Control register of unit A
(at Base Address +2h) controls the output frequency of the Dual
Frequency Time Base on both the CTM-05/A and CTM-10, unit B of
the CTM-10 receives the same output frequency.

●

ISRC2 to ISRC0 determine the interrupt source selection. The values
for ISRC2 to ISRC0 are described as follows:

– 0 = External (power-up default) qualified by AENB

or BENB

– 1 = Timer 1 Output

– 2 = Timer 2 Output

– 3 = Timer 3 Output

– 4 = Timer 4 Output

– 5 = Timer 5 Output

– 6 = None

– 7 = None

IENAB determines whether interrupts are enabled or disabled. The

●

values for IENAB are as follows:

– 0 = Disable (Power-up default; setting IENAB to 0 forces the

interrupt latch to 0 and will not allow the interrupt latch to set.)

– 1 = Enable

IL2 to IL0 determine the interrupt level selection. The values for IL2

●

to IL0 are encoded as follows:

– 0 = None (power-up default)

– 1 = IRQ3

– 2 = IRQ5

– 3 = IRQ7

– 4 = IRQ10

– 5 = IRQ11

– 6 = IRQ15

– 7 = None

Interrupt Status Register Format

The Interrupt Status registers for units A and B are read only. The unit A
Interrupt Status register is located at Base Address +3h, while the unit B
Interrupt Status register is located at Base Address +7h. The format of
these registers is shown in Table 6-3.

Table 6-3. Interrupt Status Register

The Interrupt Status Register is cleared automatically when the

Note:

interrupt status is read.

6-4 I/O Addresses and Registers

The IRQ bit reflects the state of the interrupt latch, as follows:

●

0 = Not present

1 = Present - event occurred

●

A 0-to-1 transition of the signal selected by ISRC0 to ISRC2 (Interrupt
Control register) is latched on the board and is cleared by a read of this
register (bit automatically resets after a read). Note that IENAB must be
set to 1 for the latch to set. IL2 to IL0 must be set to values in the range of
1 to 6 to generate an interrupt in the host computer.

Note:

If you are polling this bit (reading it repetitively) to determine
when the selected condition occurs, read the bit once more after it is set to
1 to ensure proper clearing.

Using DriverLINX

DriverLINX is a language and hardware independent application
programming interface designed to support Keithley’s analog, digital, and
counter/timer boards in Windows. DriverLINX is a multi-user and
multi-tasking data-acquisition resource manager providing more than 100
services for foreground and background data acquisition tasks.

DriverLINX simplifies the writing of data acquisition and control
programs for the CTM-10 and CTM-05/A boards.

DriverLINX Counter/Timer Model

DriverLINX abstracts all counter/timer hardware chips as an array of
three terminal devices. The terminals of an individual counter/timer are:

●

defines the operational task for the counter/timer channel.

defines the cycle period or divider for the counter/timer

defines high duration of the period for asymmetrical

defines the number of periods to generate.

By selecting values for these seven properties and, when necessary,
making the appropriate connections between counters, the application can
program DriverLINX to execute one of the counter/timer’s basic
operating modes or the following counter/timer operations and tasks:

●

Event counting —

16-,32-,and 64-bit counters for signals at the

Clock input.

Frequency measurement —

●

●

Interval measurement —

16- and 32-bit frequency measurement.

Measure time between two consecutive

pulses at a single input or two pulses at separate inputs.

●

Period and pulse width measurement —

Measure duration of each

cycle or half cycle.

●

Pulse generation —

Generate periodic pulse trains, variable duty

cycle waveforms, square waves, or input-modulated waveforms.

Applications may program and operate counter/timers independently, or
they may configure the operating mode for several counter/timers and
start or stop them synchronously. For hardware boards that support
interrupts, applications may program a list of timers whose current value
DriverLINX will read into a buffer on each interrupt.

The following tables show the legal values for the Clock, Gate, Output,
and Mode fields of a DriverLINX logical counter channel.

7-2 Using DriverLINX

Clocks

The Clock property, Table 7-1, specifies the source input for the abstract
counter/timer of a Logical Channel.

Table 7-1.

Internal1 always designates the onboard hardware clock.

●

Internal2...Internal5 designate lower frequency taps of the master
clock if the hardware supports this capability.

If the application uses an Internal1 clock with a Period value greater

than the hardware counter/timer supports, DriverLINX will
automatically select available hardware prescalers to obtain the
closest value to the requested Period.

DriverLINX Counter/Timer Model 7-3

Gates

The Gate property, Table 7-2, selects how the abstract counter/timer uses
the gate input of a Logical Channel. Generally, this input gates the
counting or measuring process or triggers the counter/timer operation.

chooses the output option based on the requested Mode.

DriverLINX Counter/Timer Model 7-5

Modes

The Mode property, Table 7-4, selects the type of rate generator or task
the abstract/counter timer will perform. Mode values fall into two general
groups — pulse and waveform generators and measurement tasks.

Note:

The waveform-oriented (for example, RateGen, SqWave, etc.)
generators program a single Logical Channel of an abstract counter/timer
while the task-oriented modes (for example, Frequency, Interval, etc.)
may program multiple Logical Channels.

7-6 Using DriverLINX

DriverLINX Task Model

To manage a user application’s data-acquisition requests, DriverLINX
creates tasks. A DriverLINX task consists of the set of hardware and
system resources and the board-specific protocols required to execute the
data-acquisition request. Applications can start tasks, monitor tasks, and
stop tasks by submitting Service Requests to DriverLINX.

Hardware Sharing

DriverLINX allows multiple applications to share a data-acquisition
device or allows multiple tasks to run on a device if the hardware can
support concurrent operations. To support hardware sharing and
concurrency, DriverLINX assigns resources to each task and then
compares the resource requirements of a new task with the in-use
resources of all current tasks. If the new requirements don’t conflict with
the current in-use resources, DriverLINX updates the in-use resources
and starts the task. Otherwise, DriverLINX rejects the newly requested
task.

Creating Tasks

User applications create data-acquisition tasks by setting the properties of
a Service Request to values that specify the task. The application then
submits the Service Request to DriverLINX that transforms each Service
Request into a procedure for performing the task on the requested
hardware subsystem.

If DriverLINX detects any errors in the Service Request or in the
hardware during the task, it aborts the task and returns an error code to the
application. If the application requests hardware resources that are
already in use by another thread or process, DriverLINX also stops the
task and notifies the application.

DriverLINX Task Model 7-7

Monitoring and Stopping Tasks

Applications may also check the status of a task or terminate a task by
modifying the operation property of the Service Request used to create
the task. To check status, change the operation property to “status.” To
terminate a task, change the operation property to “stop.”

DriverLINX Events

Applications can request that DriverLINX notify the application of
significant events during execution of a task. By designing a
data-acquisition task to use events, an application can overlap data
processing with data collection. Events allow the application to
coordinate these two activities without the overhead associated with
polling for the status of the data collection task and without the
scheduling problem of coordinating data processing with partial data
collection.

DriverLINX posts events to an application through the Windows
messaging mechanism. DriverLINX supports messages found in
Table 7-5:

Table 7-5.

the stop event condition in a Service Request was satisfied, or
DriverLINX detected a run-time error and stopped the task.

7-8 Using DriverLINX

The

●

BufferFilled

event notifies the application that DriverLINX has
read or written the current buffer. Applications can use this message
with multiple data buffers to eliminate polling the driver for the status
of the task and to overlap data processing with data acquisition.

●

The

DataLost

event notifies the application that DriverLINX detected
that the hardware was filling or emptying buffers faster than the
application or driver could process the buffers.

The other DriverLINX events are useful for special cases.

●

The

ServiceStart

event notifies the application that DriverLINX is
starting the task. An application might use this event to provide visual
feedback to the user interface that the task is starting.

●

The

TimerTic

processed a clock interrupt. DriverLINX only reports this event for
the counter/timer subsystem when the task is not using data buffers.

●

The

StartEvent

logical condition the application specified in the Service Request’s
Start Event as true. DriverLINX can only report this event if the
hardware generates an interrupt associated with the Start Event.

The

subsystem or configures a Logical Channel without starting the
counter.

●

When an application uses

POLLED

mode, DriverLINX starts the
counter/timer hardware running, but it does not automatically report
any status information about the task to the application.

●

When an application uses

INTERRUPT

mode, DriverLINX starts the
counter/timer hardware running with a hardware interrupt enabled. At
each interrupt, DriverLINX either sends a

TimerTic event to the
application or saves the current count of the requested counter/timers
into a data buffer.

7-10 Using DriverLINX

When using polled mode counter/timer operations, DriverLINX returns
control to the application after starting the counter/timer hardware.
Applications must use the Status operation to read the current count value
of a counter/timer. The counter/timer task will run until the application
ends it with a Stop operation.

When using interrupt mode counter/timer operations, DriverLINX also
returns control to the application after starting the counter/timer
hardware. However, if the application specified data buffers in the Service
Request, DriverLINX will automatically read and store the current
counter value(s) into the buffer. The application may request that
DriverLINX read the next Logical Channel into the Channel list at each
interrupt or that DriverLINX read all Logical Channels at each interrupt.
If the application is not using buffers, then DriverLINX sends a TimerTic
event to the application at each interrupt.

Individual and Group Tasks

Applications can control individual counter/timer channels as separate
tasks or they can synchronize the starting and stopping of multiple
channels. To collect multiple channels into a group, the application first
performs Configure operations on each channel in the group to set up the
hardware. Then the application can start the channels in the group by
executing a Service Request with a Start operation that lists the group’s
channels in the Service Request’s channel list. By using a Stop operation
instead, the application can simultaneously stop all channels in the group.

DriverLINX Task Model 7-11

Mapping Logical Channels to Counter/Timer Hardware Channels

DriverLINX maps the hardware’s counter/timer channels to consecutive
Logical Channels. Table 7-6 shows the correspondence between the
hardware channels and Logical Channels.

Note: DriverLINX uses zero-based numbering for Logical Channels.

Logical
Channels

CTM-05/A 12345

CTM-10 1A 2A 3A 4A 5A 1B 2B 3B 4B 5B

Digital I/O Hardware

The CTM-10 and CTM-05/A counter/timer boards support one or more
digital I/O ports. The CTM-05/A board has one 8-bit digital input port
with latch and one 8-bit digital output port with latch. The CTM-10 board
has two 8-bit digital input ports with latches and two 8-bit digital output
ports with latches. A strobe line input at each input port controls whether
the input data passes through the latch or is held by the latch. There is no
software control over this strobe line.

These digital ports are physically independent of the counter/timers and
do not have any internal connections to the counter/timers. Also, the
digital I/O ports do not generate any hardware interrupts. Applications
can read or write the digital ports independently of the counter/timers.
DriverLINX does not support reading a digital input port at each
counter/timer interrupt to start or stop a counter/timer task.

Table 7-6.

Counter/Timer Hardware Channels

0123456789

Map of Logical Channels to

The CTM-10 and CTM-05/A boards also have a digital input line that
generates a hardware interrupt. DriverLINX models this line as a 1-bit
digital input channel. Associated with the interrupt input line is another
external input line that enables or disables the interrupt input line.
DriverLINX has no direct hardware control over this gating line.

7-12 Using DriverLINX

Mapping Logical Channels to Digital Hardware Channels

DriverLINX maps the hardware’s digital channels to consecutive Logical
Channels. Table 7-7 shows the correspondence between the hardware
channels and Logical Channels.

Note: DriverLINX always uses zero-based numbering for Logical

Channels.

Table 7-7.

Logical Channel 0 1 2

CTM-05/A Port A I/O external interrupt

CTM-10 Port A I/O Port B I/O external interrupt

To support writing hardware-independent applications, DriverLINX
assigns special fixed Logical Channel numbers as aliases for the Logical
Channel of an external interrupt line.

Map of Logical Channels to Digital Hardware Channels

Properties of Logical Channels

The hardware design of the digital channels on the CTM-10 and
CTM-05/A boards does not support reading back the last value written to
a digital output port. Writing Logical Channel 90 outputs data to a
physically different latch than when an application reads Logical Channel

0. If needed, applications must maintain their own shadow copies of the
values written to a digital output port.

Applications that want to share an output port with another thread or
process can do so without knowing the current output value of the port.
Use either bit-level I/O or extended Logical Channel addressing. See
DriverLINX manual, DriverLINX Counter/Timer Programming Guide,
accessed from the DriverLINX CD.

Mapping Logical Channels to Digital Hardware Channels 7-13

Combining or Splitting Logical Channels

DriverLINX supports a software extension to Logical Channel addressing
that allows applications to combine adjacent Logical Channels into a
single channel or split a Logical Channel into smaller addressable parts.
For instance, applications can address individual bits on the digital I/O
board or read and write multiple channels with a single operation.

To use the Logical Channel addressing extensions for a 16-bit Logical
Channel address, combine the channel number of an addressable unit
with a size field as shown in Table 7-8.

Table 7-8.

Bits 15 14 to 12 11 to 0

Range 0 to 1 0 to 7 0 to 4095

7-14 Using DriverLINX

“Native” units refer to the hardware-defined digital channel size. For most
boards, this is the same as an 8-bit byte. When using extended Logical
Channel addressing, DriverLINX groups digital bits in units defined by
the size code and then assigns consecutive channel numbers starting from
zero. For instance, a CTM-10 with two 8-bit ports would have the
following channel addresses for each size code. See Table 7-10.

Unit Channels Address (dec) Address (hex)

native 0 to 1 0 to 1 0 to 1

bit 0 to 15 4096 to 4111 1000 to 100F

half nibble 0 to 3 8192 to 8195 2000 to 2003

byte 0 to 1 16384 to 16385 4000 to 4001

word 0 20480 5000

Implementation Notes

● For extended Logical Channel addressing of unit sizes less than the

native size, DriverLINX only supports single-value transfers.

Table 7-10. Channel Bit Groups

● For block I/O transfers, DriverLINX only allows Logical Channel

addressing at unit sizes equal to or larger than the native size. Note
that extended Logical Channels may not map to consecutive physical
channels. Because DriverLINX uses the CPU’s block I/O instructions
for polled, block I/O transfers, some bytes won’t represent I/O ports.

● When using size codes larger than the native addressing unit, you

may not be able to address all hardware ports if the number of
available digital I/O lines is not an integral multiple of the size unit.

the I/O connections. Reconnect and check the operation of the I/O
connections, one at a time.

4. If operation fails for an I/O connection, check the individual inputs
one at a time for shorts and opens.

5. If operation remains normal to this point, the problem is in the
CTM-10 or CTM-05/A board(s) originally in the computer. If you
were using more than one board, try each board one at a time in the
computer to determine which is faulty.

6. If you cannot isolate the problem, refer to the next section for
instructions on obtaining assistance.

Am9513A Counter/Timer

This appendix provides general information on how the Am9513A
counter/timer is used in the CTM-10 and CTM-05/A.

Functional Description

All data transfers to the Am9513A counter/timer use two I/O ports. Data
transfer uses the port at the base address; for example, loading and
reading counters and counter mode registers. The port at Base Address
+1h carries addressing, command, control, and status. The many internal
registers of the Am9513A require an indirect system of access using a
Data Pointer register, which is reached via the Command register. The
Command register also performs other functions such as loading and
enabling the counters, latching counter contents, etc. Acceptable
Command register codes are listed in Table C-1, on the following page.

C-2 Am9513A Counter/Timer

Note the following logical structure in the Command register codes:

●

All codes beginning with 000: reference Data Pointer register.

Codes from 001 to 110: reference counter operations.

●

Codes beginning with 111 and ending with 001-101: perform

●

single-bit counter functions.

●

Codes beginning with 111 and ending with 000 or 110-111: perform
master control functions (all these functions can also be activated by
writing the Master Mode register).

Those codes that reference counter operations use a linear select S5 to S1.
Only the counters with the appropriate S bit set are affected. This is a
powerful feature that allows simultaneous loading, latching, enabling, etc.
of any combination of the Am9513A internal counters.

Internal Register Selection

Returning to command codes that commence with 000, these codes select
the internal registers according to E and G fields that set the Data Pointer
register. The Am9513A has one Master Mode register that controls the
operation of all counters and the scaler. The Master Mode register must be
set in the initialization sequence of your program. In addition, each
counter has its own Mode, Load, and Hold registers. These registers are
accessed through the data port at the base address after setting the Data
Pointer register to address the desired register. The data format of the
Data Pointer register is as follows:

E2 E1 G4 G2 G1 BP

Byte Pointer

Group Pointer

Element Pointer

Internal Register Selection C-3

These pointers of the Data Pointer register are defined as follows:

●

Byte Pointer (BP):

– 1 = Least significant byte transferred next.

– 0 = Most significant byte transferred next.

●

Group Pointer (G4, G2, and G1):

– 000 = Illegal

– 001 = Counter Group 1

– 010 = Counter Group 2

– 011 = Counter Group 3

– 100 = Counter Group 4

– 101 = Counter Group 5

– 110 = Illegal

– 111 = Always for Control Group

Element Pointer (Counter Group E2 and E1):

●

– 00 = Mode register

– 01 = Load register

– 10 = Hold register

– 11 = Hold register (Hold Cycle increment)

Element Pointer (Control Group E2 and E1):

●

– 00 = Alarm Register 1

– 01 = Alarm Register 2

– 10 = Master Mode register

– 11 = Status Register (No increment)

The Data Pointer consists of a 2-bit Element Pointer (E), a 3-bit Group
Pointer (G), and a 1-bit Byte Pointer (B). The Byte Pointer bit indicates
which byte of a 16-bit register transfers on the next access through the
data port. Whenever the Data Pointer is loaded, the Byte Pointer (B) is set
to 1, indicating that a least significant byte of data is expected next. With
an 8-bit data bus (as used on the IBM PC), the Byte Pointer toggles after
each 8-bit data transfer (Master Mode bit MM13 = 0). The Element and
Group Pointers work together to select the internal register that is

C-4 Am9513A Counter/Timer

accessible through the data port. Although the Element and Group
Pointers in the Data Pointer register cannot be read, the Byte Pointer is
available as a bit in the Status register.

Random access to any internal location can be achieved by loading the
Data Pointer (through Base Address +1) using the command shown in
Table C-2 and then reading or writing to the location through the data port
(at base address) as appropriate.

The Counter registers are all 16-bit and after loading the pointer, data is
transferred in low-byte/high-byte sequence. The following example
shows loading the Counter 3 Load register (using BASIC):

xxx10 OUT BASE + 1, &H13 'write 000 10 011 to command reg.
xxx20 OUT BASE, 0 'low byte = 0
xxx30 OUT BASE, &H80 'high byte = 128 register loaded

'with 32,768

Internal Register Selection C-5

Many programs contain a pattern of loading the Counter Mode register,
the Load register, and the Hold register in sequence or setting Alarm
Register 1, Alarm Register 2, and the Master Mode register. The Element
Pointers are arranged to increment on each 2-byte data transfer if Master
Mode bit 14 (MM14) = 0. This arrangement saves writing to the
Command register between items of data and, depending on your
preferences, also is a feature that you may wish to use for brevity of code
or to ignore for clarity of code.

In general, most programs consist of an initialization section that sets the
overall operation of the Am9513A through the Master Mode register, then
sets each counter operating configuration through its individual mode
register, and finally loads initial data into the counters through the Load or
Hold registers. Following the initialization, the counters are usually
enabled using the Command register, possibly latched and read using the
Command and Hold registers, or disabled, re-loaded, and re-enabled, and
so on. Most of the
subsequent reading and writing operations are much simpler.

Master Mode Register

heavy

work in programming is in the initialization;

The Master Mode register controls the overall operation of the Am9513A
and should be the first register initialized by your program. The 16-bit
register functions as follows:

MM15 selects the dividers for the four counters in the crystal oscillator
scaler. The scaler stages can divide by either 10 or 16 (BCD or binary)
according to whether MM15 is 1 or 0. The fundamental crystal frequency
F1 (1MHz) and each of the scaler outputs F2, F3, F4, and F5 can be
routed to any of the counters and the FOUT divider by software control.

C-8 Am9513A Counter/Timer

For instance when MM15 = 1 (BCD), the frequencies are as follows:

●

F1 = 1MHz

F2 = 100kHz

●

F3 = 10kHz

●

●

F4 = 1kHz

●

F5 = 100Hz

The structure of the crystal oscillator scaler is shown in Figure C-1.

MM14 selects automatic incrementing of the Data Pointer register.
MM14 can also be individually controlled through the Command register.

MM13 selects the Data Bus Width and, for IBM PC operation, should
always be zero (8-bit bus). MM13 can also be individually controlled by
the Command register.

MM12 controls operation of AFOUT (pin 30 on the CTM-05). When
MM12 is low, AFOUT is enabled. When MM12 is high, AFOUT is at a
logic low (note this is not a tri-state output). MM12 can also be
individually controlled through the Command register.

MM11 through MM8 set the divider modulus for the AFOUT divider (not
to be confused with the oscillator scaler). This is a 4-bit divider counter
ahead of the AFOUT output. Any modulus from 1 to 1 is possible.

F5

Master Mode Register C-9

MM7 through MM4 set the input source of the AFOUT divider. This can
be any of the oscillator scaler outputs F1 to F5, any of the counter gate
inputs GATE 1 to 5, or any of the external source inputs SOURCE 1 to 5.

MM3 and MM2 set the comparison modes for counters 2 and 1. If these
bits are set, the comparator outputs are substituted for the normal counter
outputs on counter out 1 and 2 (Pins 35 and 34). The comparator output is
active high if the output control field of the Counter Mode register is 001
or 010 and active low for a code of 101. Once the compare output is true,
it will remain so until the count changes and the comparison therefore
goes false.

Finally, MM1 and MM0 set the optional Time Of Day Mode for counters
1 and 2. When both these bits are zero, counters 1 and 2 operate in exactly
the same way as all the other counters. For other combinations of these
bits, the counter division ratios are set so that the most significant byte of
counter 2 is hours, the less significant byte is minutes and the most
significant byte of counter 1 is seconds. The least significant byte section
of counter 1 becomes a pre-scaler in this mode and can divide by 50, 60,
or 100 for 50Hz, 60Hz, or 100Hz (crystal) input frequencies.

Counter Mode Registers

Each counter has its own mode-register controls to control its operation.
The Counter Mode registers should be initialized after the Master Mode
register. Each register is 16 bits, as follows.

CM7 to CM3 control how the counter operates, using the following
counts:

– 0XXXX = Disable special gate

– 1XXXX = Enable special gate

– X0XXX = Reload from Load

– X1XXX = Reload from Load or Hold

– XX0XX = Count once

– XX1XX = Count repetitively

– XXX0X = Binary count

– XXX1X = BCD count

– XXXX0 = Count down

– XXXX1 = Count up

●

CM12 to CM8 control the clock input source for the counter, using
the following counts:

– 0XXXX = Count on rising edge

– 1XXXX = Count on falling edge

– X0000 = TCN - 1

– X0001 = SRC 1
