Introduction

F81801 OPEN 

BOOL F81801U_Open()
{
	outb(0x87, 0x2e);
        outb(0x87, 0x2e);

	if (F81801U_Read(CHIP_ID_REGISTER1) == CHIP_ID_DEFAULT_VALUE1 && F81801U_Read(CHIP_ID_REGISTER2) == CHIP_ID_DEFAULT_VALUE2)
           return TRUE;
	return FALSE;
}

F81801 CLOSE 

void F81801U_Close()
{
	outb(0xaa,0x2e);
}

Initial internal F81801 

void F81801U_Init()
{
	 F81801U_Write(Logic_Device_Number_Register, GPIO_Device_Configuration_Registers);// GPIO Device Configuration Registers (LDN CR06) 
 
	 F81801U_Write(GPIO3_Output_Enable_Register, 0xf0);//GPIO34~GPIO37 OUTPUT SET / GPIO30~GPIO33 INPUT SET
	 F81801U_Write(GPIO3_Drive_Enable_Register, 0xf0);//GPIO34~GPIO37 DRIVE SET

}

F81801U READ 

DWORD F81801U_Read(DWORD dwAddrVal)
{
	DWORD dwPortVal;
	outb(dwAddrVal, 0x2e );
        dwPortVal=inb( 0x2f );

	return (dwPortVal & 0x00FF);
}

F81801U WRITE 

void F81801U_Write(DWORD dwAddrVal, DWORD dwPortVal)
{
 	outb(dwAddrVal, 0x2e );
        outb(dwPortVal, 0x2f );
}

F81801U GetDigitalInput

BYTE F81801U_GetDigitalInput()
{
	CString tmp;
	BYTE byteGPIO3X = 0;
	BYTE byteData = 0;
	byteGPIO3X = F81801U_Read(GPIO3_Pin_Status_Register);
	byteData = byteGPIO3X & 0x0F;

	return byteData;
}

F81801U SetDigitalOutput 

void F81801U_SetDigitalOutput(BYTE byteValue)
{
	BYTE byteData = 0;

	byteData = (byteValue & 0x01) ? byteData + 0x10 : byteData;
	byteData = (byteValue & 0x02) ? byteData + 0x20 : byteData;
	byteData = (byteValue & 0x04) ? byteData + 0x40 : byteData;
	byteData = (byteValue & 0x08) ? byteData + 0x80 : byteData;

	F81801U_Write(GPIO3_Output_Data_Register, byteData);
}
