1.2 Attentions
1) Notes under a table or figure indicate the difference of models, or alternative definition of specific
pin of the header (jumper/connector).
2) How to identify the first pin of a header or jumper
Usually, there is a thick line or a triangle near the header’s or jumper’s pin 1.
Square pad, which you can find on the back of the motherboard, is usually used for pin 1.

Notes:
[1]: Due to the restriction of Windows 32 bit OS, when applied more than 4G memory, 32 bit OS may
detect less than actual size.
[2]: LAN can be customized into single LAN.
[3]: mSATA and Mini PCI-E are using the same interface, so only one function can be used at one time,
if you need the other function, it would need some hardware changes supported.
[4]: COM3 can be RS232 or RS485 by setting jumpers.

6. BIOS setup
See “SV1-H612A BIOS User Manual” for detail information of BIOS setup.
7. GPIO & Watchdog
7.1 Read and write GPIO
The motherboard provides 8 GPIOs (General Purpose Input and Output register). The GPI
(General Purpose Input register) is a read only register bit. It reflects the incoming logic levels of the I/O
pins, and any writes are ignored. The GPO (General Purpose Output register) is a read and write
register bit. Reads from it reflect the value that is in the flip-flop controlling the output.
The following example shows method to read and write GPIO with Borland C Compile environment
under windows.
void
main(void){ UINT
16 Addr = 0;
UINT8 Bit = 0;
BOOLEN GpioValue1, GpioValue2 = 0;
// read value from gpio<Addr,Bit>.
GpioValue1 = ReadGpio(Addr, Bit);
// write value to gpio<Addr,Bit>.
Status = WriteGpio(Addr, Bit, GpioValue2);
}
UINT8 ReadGpio(UINT8 Addr, UINT8
Bit){ return (inportb(Addr) & (1<<Bit)) >>
Bit;
}
UINT8 WriteGpio(UINT8 Addr, UINT8 Bit, UINT8
Value){ if(Value == 0 || Value == 1){
outportb(Addr, inportb(Addr) & (~(1<<Bit)) | Value<<Bit);
return TRUE;
}
else
return FALSE;
}
7.2 Set & Disable WatchDog
The following example shows method to Set & Disable WatchDog with Borland C Compile
environment under windows.
void main(void){
UINT16 TimeValue = 3;
SetupWDT(TimeValue); //if halted for TimeValue minutes, system will reboot automaticly.

DisableWDT(TimeValue); //used to disable watchdog.
}
void SetupWDT(UINT16 TimeValue){ //Enable
WatchDog Superio_Set_Reg(0x7,0xf1,0x44);
Superio_Set_Reg(0x7,0xf4,0x1e);
Superio_Set_Reg(0x7,0x71,0x00);
Superio_Set_Reg(0x7,0x72,0x90);
Superio_Set_Reg(0x7,0x73,(TimeValue&0xFF));
Superio_Set_Reg(0x7,0x74,(TimeValue>>8));
}
void DisableWDT(UINT16 TimeValue){ //Disable
WatchDog Superio_Set_Reg(0x7,0xf1,0x00);
Superio_Set_Reg(0x7,0xf4,0x00);
Superio_Set_Reg(0x7,0x71,0x00);
Superio_Set_Reg(0x7,0x72,0x20);
}
void Superio_Set_Reg(UINT8 bLDN, UINT8 bReg, UINT8
bValue){ Superio_Enter_Config();
IoWrite8(0x2E,0x07); //Set LDN
IoWrite8(0x2F,bLDN);
IoWrite8(0x2F,bReg);
IoWrite8(0x2F,bValue);
Superio_Exit_Config();
}
void Superio_Enter_Config(void){ //enter superio’s configuration
mode IoWrite8(0x2E,0x87);
IoWrite8(0x2E,0x01);
IoWrite8(0x2E,0x55);
IoWrite8(0x2E,0x55);
Sleep(100);
IoWrite8(0x2E,0x22);
IoWrite8(0x2F,0x80);
}
void Superio_Exit_Config(void){ //exit superio’s configuration mode
IoWrite8(0x2E,0x02);
IoWrite8(0x2F,0x02);
}
【End】
