Introduction

Thank you for purchasing the ZiLOG Z8 GP In-Circuit Emu lator (ICE) and Develop ment
Platform, ZGP323ICE15ZEM. The Z8 GP ICE provides Z8 GP family chip emulation
with a trace and event system for program debugging using ZDS II development tools.
Once your code is complete, use the included OTP programming module to burn your
design to OTP devices.

This startup guide tells you how to:

1. Install ZDS II software.

2. Configure the Z8 GP ICE for connection to your PC.

Note:

3. Use a target POD to connect the Z8 GP ICE to a target board such as the Z8 GP
ZGP323 evaluation board (included) with a 20-, 28-, or 40-PDIP socket. (Converters
for 20- and 28-SOIC and 20-, 28-, and 48-SSOP sockets are available in the adapter
kits described on page 23.)

The kit includes a 28-PDIP target POD and programming adapter. Target
PODs and adapter support for other packages must be ordered separately. See
section “Adapter Kit Ordering Information” on page 23 for details.

4. Connect the Z8 GP ICE to a supplied OTP programming module.

5. Use the supplied OTP programming module with ZDS II software to program a 20-,
28-, or 40-PDIP Z8 GP family device. (Adapters for 20- and 28-SOIC and for 20-, 28­and 48-SSOP packages are available in the adapter kits described on page 23.)

6. Run a demonstration program to verify proper operation, illustrate basic operation of
the trace and event system, and burn a Z8 GP OTP device using the OTP program­ming module.

Install the Hardware

The Z8 GP ZGP323 ICE and Development Platform features an Ethernet interface and an
RS-232 serial port. Hardware installation consists of:

• Installing a target POD into a 20- or 28-PDIP socket on a target development board,

such as the Z8 GP ZGP323 evaluation board (included);

• Connecting the Z8 GP ICE to the target POD;

Install the Software UM019301-0505

Z8 GP™ ZGP323 In-Circuit Emulator and Development Platform

User Manual

Page 3

• Connecting the Z8 GP ICE to the OTP programming module; and

• Connecting the Z8 GP ICE to a PC.

You may have to reconfigure network settings on the PC or on the Z8 GP ICE before using
the emulator.

Installing a Target POD onto a Target Development Board

The Z8 GP ICE kit is ideal for use with a Z8 GP ZGP323 evaluation board (included, see
Figure 1) as a target development board. The 20-, 28, and 40-PDIP target PODs plug into
the associated PDIP sockets on the development platform.

If you are using a different target development board, use an appropriate target POD and
pin converter to connect the Z8 GP ICE to the board. For example, if your target board has
a 20-SOIC socket, mate the 20-PDIP target POD onto the 20-PDIP to 20-SOIC converter.
Then install the target POD and converter assembly into the board’s 20-SOIC socket.

Note:

If you are not using a target development board, insert the 34-pin null target
connector, p/n 93c0086-001, into Z8 GP ICE target interface connector P16.

Connecting the Z8 GP ICE to the Target POD

Once you have installed the appropriate target POD (and converter, if required) onto the
target development board, connect the Z8 GP ICE to the target POD as follows:

• 40-PDIP target POD:

– Connect the 16-circuit cable from P17 on the emulator to P17 on the 40-PDIP tar-

get POD.

– Connect the 34-circuit cable from P16 on the emulator to P16 on the 40-PDIP target

POD.

• 20-PDIP and 28-PDIP target PODs: Connect the 34-circuit cable from P16 on the

emulator to P16 on the target POD. (Emulator connector P17 is not used.)

Connecting the Z8 GP ICE to the OTP Programming Module (Optional)

After developing and debugging your so ftware, use the following instructions to connect
the Z8 GP ICE to the OTP programming module so you can burn your code onto chips.

1. Connect the 40-circuit ribbon cable from the Z8 GP ICE O TP Programming co nnector
to connector P1 on the OTP programming module.

2. The 40-PDIP ZIF socket on the OTP programming module is designed to accept 40­PDIP OTP chips. The OTP programming adapters (see Table 4 on page 24) allow you
to adapt the ZIF socket to accept 20-SOIC, 20-SSOP, 20-PDIP, 28-SOIC, 28-SSOP,
28-PDIP, and 48-SSOP chip packages.

Once you have installed the OTP chip into the ZIF socket (or programming adapter), you
are ready to program the chip using the instructions in “OTP Programming” on page 18.

Running a Sample Project

After installing the ZDS II software and setting up the hardware, you can run a sample
software project to verify proper emulator operation and experiment with the trace and
event system. This section describes how to run the emulator in in-circuit mode.

Note:

If you run the emulator with a target attached, be aware that the emulator’s
voltage comparator is designed as a target power sensor, not as a precision
voltage measurement device. If you set the Target VCC to match your target
and the target’s voltage drifts downward, the power sensor may no longer
detect it. The emulator may therefore not connect to the target. In such cases,
set the Target VCC voltage progressively lower until you get a good connec­tion.

The sample project ledblink_c.pro is included in the ZDS II sample directory, located in:

and the ZDS II—Z8 GP User Manual (UM0178), located in the docs directory
of the ZDS II CD-ROM.

Collecting a Simple Trace

16. Now we’ll collect a simple trace by starting the program, then stopping it and viewing
the trace buffer. Click the Go button ( ) in the toolbar, wait a moment, and then
press the Break button ( ). The trace buffer acts as a ring buffer that continuously
fills and then overwrites itself until you stop execution.

17. Open the Trace window by selecting

Get Frames to display the trace information.

Using an Event to Stop Execution

Events allow you to stop execution based on more complex conditions than a simple
instruction address.

The following events are available:

• Program counter position, with mask.

• Data on Port0 (state of its pins), with mask.

• Data on Port2 (state of its pins), with mask.

• Data on Port3 (state of its three input pins), with mask.

• External Trigger In (0 or 1).

Let’s define a simple event and see how it works.

1. Select Tools --> Trace and Event System. The Trace and Event System window
appears (Figure 10).

Go button or by selecting Build –> Debug –> Go.

9. When the program counter reaches 06B2, execution stops on event match.

10. Click

Get Frames to display the trace information. Study the contents of the Trace

window to see how the trace and event system reports program execution for the seg­ment we set using the Event tools.

Collecting Trace Before and After an Event

You can also use the Trace and Event System to capture trace data before and after an
event. Set up your events as described in “Using an Event to Stop Execution” on page 16.
In the Then: section, click the Event Position in Buffer radio button instead of Break. Use
the slider to select the number of cycles from the 64K buffer to be captured before and
after the event.

In this case, all cycles are traced until the event is detected, then the selected number of
cycles after the event are collected. Execution stops after the cycles are collected. What
remains in the trace buffer are the selected number of cycles after the event. The remainder
of the 64K frames contain cycles before the event occurred.

If you move the slider all the way to the left, only cycles before the event are captured. If
you move the slider all the way to the right, only cycles after the event are captured.

Single-Stepping Through a Program

ZDS II provides a simple mechanism for single-stepping through a program. To single­step through a program:

1. Reset the program to Main() by either the Reset icon or with

14. If you do not want a serial number loaded into the part, select the None button in the
Method area. To load a serial number:

a. Select the Sequential or Pseudorandom button to determine how the serial number

is incremented on subsequent burns.

b. Select the size of the serial number (1, 2, 3, or 4 bytes) in the Serial Number Size

area.
c. Enter the starting serial number in the Serial Number field.
d. Enter the address into which you want the serial number loaded in the Address

field.

15. Click Blank Check to verify that the OTP chip is actually blank.

16. Click the Burn button to program the OTP chip with the contents of emulator RAM.
As part of the Burn function, the OTP chip is also verified.

17. When the burn is complete, click OTP checksum to calculate the checksum of data on
the OTP chip and compare it to the RAM checksum calculated earlier.

18. Click Close to close the OTP Programming window.

LED Indicators

There are three sets of dual LED indicators on the Z8 GP ICE (see Figures 3 and 5):

• The dual ICE RUN LED on the front panel indicates emulator status. If the top LED is

lit, the emulator is executing your system code. When the top LED is off, emulation
has stopped. If the bottom LED is lit, the emulator is not functioning properly . Contact
technical support at http://www.zilog.com for assistance.

• The dual 3.3VDC/1.8VDC LED on the rear panel indicates the status of internal volt-

ages. Both LEDs are normally illuminated when power is connected.

• The dual LAN/LINK LED on the rear panel indicates Ethernet status. The LINK LED

indicates that the Ethernet connection is live. The LAN LED indicates that data is
being transferred across the connected network.

External Interface Connectors

There are five external interface connectors on the Z8 GP ICE. Connectors P16 and P17
are used to connect the emulator to the target POD and adapter board assembly. (See Fig­ure 4.)

The OTP Programming connector P15 is used to connect the emulator to the OTP pro­gramming module.

Connector J8 on the emulator front panel (see Figures 4 and 5) provides a ground connec­tion on all three pins.

Connector J9 on the emulator front panel (see Figures 4 and 5) provides access to the fol­lowing functions:

• Pin 3 provides a HIGH external trigger out for use in triggering a device such as a

logic analyzer or oscilloscope. Pin 3 is under software control, and can be set to acti­vate through the ZDS II trace and event system. The trigger can be set to toggle or
pulse.

• Pin 1 provides an input for an external HIGH or LOW trigger in, allowing use of an

external trigger as an event for the ZDS II trace and event system.

Using J9 Pin 3, External Trigger Out

The Z8 GP ICE external trigger out feature is always enabled. Set your trace and event
system parameters, then run your code. When the event you set up occurs, pin 3 of con­nector J9 goes HIGH and stays HIGH as long as the event is active. The bigger the event
window, the longer trigger out stays HIGH.

How to Set Connector J9 Pin 1, External Trigger In (see Figure 5 on page 6)

To use the Z8 GP ICE external trigger in feature:

1. With the ledblink_c.pro project open in ZDS II as described in “Running a Sample
Project” on page 14, select

2. In the
check the

Trace and Event System window, select an Event entry. In the When section,

Trigger In box.

Tools > Trace and Event System.

3. Select either 0 or 1 to trigger on trigger low or high, respectively (edge-triggering not
supported).

4. Click the OK button to set the trace and event system parameters. If you set trigger=1
in the

Trace and Event System window, then a HIGH on pin 1 of connector J9 gener-

ates an event in the ZDS II trace and event system. If you set trigger=0, then a LOW
on pin 1 of connector J9 generates an event.
