Introduction

Initial Internal F75111 port address (0x9c)

   define GPIO1X, GPIO2X, GPIO3X to input or output 
   and Enable WDT function pin 

Set F75111 DI/DO ( sample code as below Get Input value/Set output value )

   DI: InterDigitalInput()

PULSE mode

Sample to setting GP33, 32, 31, 30 output 1mS low pulse signal.

{ 
    this->Write_Byte(F75111_INTERNAL_ADDR, GPIO3X_PULSE_CONTROL,       0x00);             //This is setting low pulse output
    this->Write_Byte(F75111_INTERNAL_ADDR, GPIO3X_PULSE_WIDTH_CONTROL, 0x01);             //This selects the pulse width to 1mS
    this->Write_Byte(F75111_INTERNAL_ADDR, GPIO3X_CONTROL_MODE,        0x0F);             //This is setting the GP33, 32, 31, 30 to output function.    
    this->Write_Byte(F75111_INTERNAL_ADDR, GPIO3X_Output_Data ,        0x0F);             //This is setting the GP33, 32, 31, 30 output data.
}

Initial internal F75111

void CKey_Pad_utilityDlg::InitInternalF75111()
{
    ::Write_Byte(F75111_INTERNAL_ADDR,GPIO1X_CONTROL_MODE  ,0x00);        //set GPIO1X to Input  function     
    ::Write_Byte(F75111_INTERNAL_ADDR,GPIO3X_CONTROL_MODE  ,0x00);        //set GPIO3X to Input  function
    ::Write_Byte(F75111_INTERNAL_ADDR,GPIO2X_CONTROL_MODE  ,0x00);        //set GPIO2X to Input function
}
