3. I/O Control Register

3.1 How to Find the I/O Address

The plug & play BIOS will assign a proper I/O address to every OME-PCI-

TMC12(A) card in the power-on stage. The IDs of OME-PCI-TMC12(A) are given

as following:

• Vendor ID = 10B5

• Device ID = 9050

• Sub-vendor ID= 2129

• Sub-device ID = 9912

We provide all necessary functions as following:

1. PTMC12_DriverInit(&wBoard)

This function can detect how many OME-PCI-TMC12(A) cards in the system.

It is implemented based on the PCI plug & play mechanism. It will find all

OME-PCI-TMC12(A) cards installed in this system & save all their resource

in the library.

• wBoard=1 Æ only one OME-PCI-TMC12(A) in this PC system.

• wBoard=2 Æ there are two OME-PCI-TMC12(A) in this PC system.

2. PTMC12_GetConfigAddressSpace(wBoardNo,*wBase,*wIrq,*wPLX)

The user can use this function to save resource of all OME-PCI-TMC12(A)

installed in this system. Then the application program can control all

functions of OME-PCI-TMC12(A) directly.

• wBoardNo=0 to N Æ totally N+1 cards of OME-PCI-TMC12(A)

• wBase Æ base address of the board control word

• wIrq Æ allocated IRQ channel number of this board

• wPLX Æ base address of PCI-interface-IC

The plug & play BIOS will assign the proper I/O address to OME-PCI-TMC12.

If there is only one OME-PCI-TMC12, the user can identify the board as card_0. If

there are two OME-PCI-TMC12 cards in the system, the user will be very difficult

to identify which board is card_0? The software driver can support 16 boards max.

Therefore the user can install 16 boards of OME-PCI-TMC12 in one PC system.

How to find the card_0 & card_1 ?

The simplest way to find the card number is to use DEM10.EXE given in

DOS demo program. This demo program will send a value to D/O and read back

from D/I. If the user installs a 20-pin flat cable between CON2 & CON3, the value

read from D/I will be the same as D/O. The operation steps are given as following:

1. Remove all 20-pin flat cable between CON2 and CON3

2. Install all OME-PCI-TMC12 cards into this PC system

3. Power-on and run DEM10.EXE

4. Now all D/I values will be different from the D/O values

5. Install a 20-pin flat cable into CON2 & CON3 of any OME-PCI-TMC12

card

6. There will be one card’s D/I value = D/O value, the card number is also

show in screen

Therefore the user can find the card number if he install a 20-pin flat cable into

OME-PCI-TMC12 sequentially.

3.3 The I/O Address Map

The I/O address of OME-PCI-TMC12(A) is automatically assigned by

the main board ROM BIOS. The I/O address can also be re-assigned by user.

It is strongly recommended to the user to not change the I/O address.

The plug & play BIOS will assign proper I/O address to each OME-PCI-

TMC12(A). The hardware I/O ports are described as following:

The interrupt of OME-PCI-TMC12 is level-trigger. The interrupt signal can be

programmed active-low or active-high. The procedures of programming are

given as following:

OME-PCI-TMC12(A) User Manual (Ver. 2.0, Sep/2002) --- 24

1. make sure the initial level is High or Low

2. if the initial state is High Æ set the interrupt signal is active_low initially

3. if the initial state is Low Æ set the interrupt signal is active_high initially

4. If the interrupt signal is active Æ program will transfer into the interrupt

service routine Æ toggle the active_state before return from the ISR.

Example 1: assume initial level=High

Initial=High

Initial_sub()

{ now_int_state=1

_outpd(wPLX+0x4c,0x41)

(INT signal is active_Low)

ISR_sub()

{

If (now_int_state==0) /* old state=low Æ change to high now */

{

now_int_state=1; /* now int_signal is High */

*** application codes are given here ***

_outpd(wPLX+0x4c,0x41);/* active Low */

}

else /* old state=highÆ change to low now */

{

now_int_state=0; /* now int_signal is Low */

*** application codes are given here ***

_outpd(wPLX+0x4c,0x43);/* active High */

}

if (wIrq>=8) outportb(A2_8259,0x20); /* EOI */
outportb(A1_8259,0x20); /* EOI */

}

OME-PCI-TMC12(A) User Manual (Ver. 2.0, Sep/2002) --- 25

Example 2: assume initial level=Low

Initial=Low

Initial_sub()

{ now_int_state=0

_outpd(wPLX+0x4c,0x43)

(INT signal is

ISR_sub()

{

If (now_int_state==0) /* old state=low Æ change to high now */

{

now_int_state=1; /* now int_signal is High */

*** application codes are given here ***

_outpd(wPLX+0x4c,0x41);/* active Low */

}

else /* old state=highÆ change to low now */

{

now_int_state=0; /* now int_signal is Low */

*** application codes are given here ***

_outpd(wPLX+0x4c,0x43);/* active High */

}

if (wIrq>=8) outportb(A2_8259,0x20); /* EOI */
outportb(A1_8259,0x20); /* EOI */

}

So the ISR_sub( ) will be active on the rising edge & falling edge of the

interrupt signal. Refer to demo7.c, demo11.c, demo12.c & demo13.c for more

information.

3.4 New features of OME-PCI-

TMC12A

3.4.1 Default Settings of OME-PCI-TMC12A

The default settings of J28 (when board is shipped) on OME-PCI-

TMC12A(Sec. 3.4.4) makes it is equivalent to OME-PCI-TMC12. So the interrupt

system of OME-PCI-TMC12A in the default setting is compatible to OME-PCI-

TMC12. Refer to Sec. 3.4.4 for interrupt block diagram of OME-PCI-TMC12 &

OME-PCI-TMC12A.

All Xor? of OME-PCI-TMC12A are clear to their Low states in the first

power-up stage, so all clock sources of OME-PCI-TMC12A are compatible to

those of OME-PCI-TMC12. Refer to Sec. 3.4.2 for block diagram.

As shipped the OME-PCI-TMC12A is used as an OME-PCI-TMC12. All old

application programs designed for OME-PCI-TMC12 can be executed in

OME-PCI-TMC12A without any modification.

Key point Æ Default factory settings of OME-PCI-TMC12A

makes it equivalent to an OME-PCI-TMC12

The new features of OME-PCI-TMC12A are given as follows:

z The new interrupt mechanism (Sec. 3.4.4)

z The Xor? bits for 2 clocks generation (Sec. 3.4.2)

z There are 3 LEDs for status indicators (Sec. 3.4.3 & Sec. 2.1)

z It equips one smith trigger buffer for the selected clock source (Sec. 3.4.2)

z One new D/O port, wBase+0x18, for Xor-bits, XorInt & LED on/off control.

Refer to Sec. 3.4.3 for more information.

z One new D/I port, wBase+0x18, for interrupt enable. The initial routine &

ISR must inport from wBase+0x18 to enable next interrupt operation. Refer to

Sec. 3.4.4 for more information.

z Refer to new demo programs given in Sec. 3.4.5 for using these new features.

z Refer to Sec. 2.1 for PCB layout of OME-PCI-TMC12A

The new features of OME-PCI-TMC12A are given as follows:

z A schmidt trigger buffer is added to remove noises in the selected clock

source

z A Xor-control register is added to invert/non-inverted the selected clock

source. This mechanism can be used to generate 2 extra starting clocks to

8254.

Note: The Xor-control register is clear to 0 when the OME-PCI-TMC12A is

first power-up. So the initial state of OME-PCI-TMC12A is exactly compatible to

OME-PCI-TMC12.

Refer to Sec. 5.15 Ndemo2: Generate 2 Clocks, the twelve Xor-bits are used to

generate the 2 starting clocks. So the initial value of 8254 can be verified after these 2

starting clocks are generated. Then they are used to generate one single clock for

testing. In general, these Xor-bits are designed for generation of 2 starting clocks only.

Note 2. All bits of this register will be clear to zero in the power-up stage.

Xor1 --> invert/non-invert the selected clock source of CLK1

Xor2 --> invert/non-invert the selected clock source of CLK2

……………………………………………………………………

Xor11 --> invert/non-invert the selected clock source of CLK11

Xor1 2--> invert/non-invert the selected clock source of CLK12

Xor?=0 --> non-invert, it is the power-up value

Xor?=1 --> invert

---------------------------------------------------------------------------------

XorInt-->inverted/non-inverted the selected interrupt source

Led1 --> Led1=0 --> Turn LED1 ON, Led1=1 --> turn LED1 Off

Led2 --> Led2=0 --> Turn LED2 ON, Led2=1 --> turn LED2 Off

Led3 --> Led3=0 --> Turn LED3 ON, Led3=1 --> turn LED3 Off

z The Xor? is designed to generate the starting 2 clocks for 8254

z The XorInt is used to invert/non-invert the interrupt source to Low state, that is

to say, if the initial value of interrupt source is High, set this bit to High to

invert it to Low state. Refer to Sec. 5. 18 Ndemo5:Active Low Int for demo

program.

z When the TMC12A is first powered up, the initial values are all zero. So

Led1/2/3 are all turned ON. The Led1/2/3 are designed as status indicators. User

can use them based on their need.

Refer to Sec. 5.15 Ndemo2: Generate 2 Clocks, the twelve Xor-bits are used to

generate the 2 starting clocks. So the initial value of 8254 can be verified after these 2

starting clocks are generated. Then they are used to generate single clock for testing.

In general, these Xor-bits are designed for generation of 2 starting clocks only.

The interrupt mechanism of OME-PCI-TMC12 can be active Low or active High.

And the interrupt system of PCI bus is level trigger. So the Windows driver of OME-

PCI-TMC12 must create a thread to handle all interrupt active conditions. There are so

many possible conditions and hence could affect the interrupt performance.

The new interrupt mechanism of OME-PCI-TMC12A is designed to improve the

performance of Windows driver as follows:

z initial subroutine & ISR will inport from wBase+0x18 to pre-set

int_signal_to_PC (Q in Sec. 3.4.4) to High state to enable the next interrupt

operation

z if the initial value of interrupt source is Low, set XorInt to 0 Æ rising-edge

interrupt

z if the initial value of interrupt source is High, set XorInt to 1 Æ falling-edge

interrupt

z the software driver is designed for rising-edge or falling-edge interrupt

When the interrupt ISR is executed, the int_signal_to_PC (Q in Sec. 3.4.4) is in

Low state, so the interrupt ISR must inport from wBase+0x18 to pre-set

int_signal_to_PC to High state to enable next interrupt operation. Refer to Sec. 5.16,

Sec. 5.17 & Sec. 5.18 for demo program
