1.7 Connector Definitions

The following sections provide pin definitions and detailed description of all on-board

connectors. The connector definitions follow the following notation:

Column

Name Description

Pin Shows the pin-numbers in the connector. The graphical layout of the

connector definition tables is made similar to the physical connectors.

Type

Al Analog Input.

AO Analog Output.

I Input, TTL compatible if nothing else stated.

IO Input / Output TTL compatible if nothing else stated.

IOT Bi-directional tri-state IO pin.

IS Schmitt-trigger input, TTL compatible.

IOC Input / open-collector Output, TTL compatible.

IOD Input / Output, CMOS level Schmitt-triggered (open drain output).

NC Pin not connected.

O Output, TTL compatible.

OC Output, open-collector or open-drain, TTL compatible.

OT Output with tri-state capability, TTL compatible.

DIFF Differential Signal.

PWR Power supply or ground reference pins.

Signal The mnemonic name of the signal at the current pin. The notation ―XX#‖

states that the signal ―XX‖ is active low.

Note Special remarks concerning the signal.

The abbreviation TBD is used for specifications which are not available yet or which are not

sufficiently specified by the component vendors.

Appendix A: Watch Dog Timer

The working algorithm of the WDT function can be simply described as a counting

process. The Time-Out Interval can be set through software programming. The

availability of time-out interval is set by software.

The System Board allows users control WDT through dynamic software programming.

The WDT starts counting when it is activated. It sends out a signal to system reset,

when time-out interval ends. To prevent the time-out interval from running out, a

re-trigger signal will need to be sent before the counting reaches its end. This action

will restart the counting process.

WDT program should keep the counting process running under normal condition.

WDT should never generate a system reset unless the system runs into troubles.

The related Control Registers of WDT are all included in the following sample program

that is written in C language. User can fill a non-zero value into the Time-out Value

Register to enable/refresh WDT. System will be reset after the Time-out Value to be

counted down to zero. Or user can directly fill a zero value into Time-out Value

Register to disable WDT immediately.

To ensure a successful accessing to the content of desired Control Register, the

sequence of following program codes should be step-by-step run again when each

register is accessed.

For more information about WDT, please refer to Fintek F81866A data sheet.

There are two PnP I/O port addresses that can be used to configure WDT,

1) 0x2E:EFIR (Extended Function Index Register, for identifying CR index number)

2) 0x2F:EFDR (Extended Function Data Register, for accessing desired CR)

Below are some example codes, which demonstrate the use of WDT.

outp(0x2E, 0x87);

// Select Logic Device 7

outp(0x2E, 0x2C);

outp(0x2F, inp(0x2F) & 0xDF);

//Clear WDTO# Status

// Set Time-out Value

outp(0x2E, 0xF6);

outp(0x2F, Time-out Value Register );

// Counting of watch dog time is enable.

outp(0x2E, 0xF5);


// Exit Extended Function Mode

outp(0x2E, 0xAA);

80

Definitions of Variables:

Value of Count-mode Register :

1) 0x00 -- Count down in seconds (Bit3=0)

2) 0x08 -- Count down in minutes (Bit3=1)

Value of Time-out Value Register :

1) 0x00 -- Time-out Disable

2) 0x01~0xFF -- Value for counting down

81

Appendix B: GPIO

The System Board provides 4 dedicated output ports and 4 programmable I/O ports

that can be individually configured to perform a simple I/O function. Users can

configure 4 programmable I/O ports to become an input or output port by

programming register bit of I/O Selection .To invert port value, the setting of Inversion

Register has to be made (Note). Port values can be set to read or write through Data

Register.

Note: Only 4 programmable I/O ports support.

Additionally, 4 Digital Output ports amplified signals from GPIO ports. There are

open-drain buffers, which can offer greater driving capacity up to 100mA.

For more information about GPIO, please refer to Fintek F81866A data sheet.

The related Control Registers of GPIO are all included in the following sample

program that is written in C language. To ensure a successful accessing to the content

of desired Control Register, the sequence of following program codes should be

step-by-step run again when each register is accessed.

There are two PnP I/O port addresses that can be used to configure GPIO ports,

1) 0x2E - EFER (Extended Function Enable Register, for entering Extended Function

Mode)

- EFIR (Extended Function Index Register, for identifying CR index number)

2) 0x2F - EFDR (Extended Function Data Register, for accessing desired CR)

Below are some example codes, which demonstrate the use of GPIOs.

// Enter Extended Function Mode

Definitions of Variables:

Each bit in the lower nibble of each Register represents the setting of a GPIO port.

Super IO Pin Pin Name Bit GPIO DIO

111 GPIO80 0 GPIO DIO-In0




115 GPIO84 4 GPIO DIO-Out0




Value of Output Data / Input Data :

If a port is assigned to be an output port, then its respective bit can be

read/written.

If a port is assigned to be an input port, then its respective bit can be read only.

Note:

DIO-IN0/DIO-IN1/DIO-IN2/DIO-IN3 are programmed as Inputs by BIOS default.

Parameter Conditions

VinH min +1.857V

VinL max +0.525V

Rated Vin -8V ~ +12V

NC Status High by Default

** Attention: If DIO-IN0/DIO-IN1/DIO-IN2/DIO-IN3 are programmed as Output signal, they

can only offer a normal signal transfer.(NOT amplified signals.)


VoutH 3.3V thru 10k

VoutL 0V thru 1k

DIO-OUT0/DIO-OUT1/DIO-OUT2/DIO-OUT3 are fixed as Outputs by BIOS.


Open-drain buffer Power-on default = Open

Driving Capacity max 100mA continue
