Sample Code:
GPI_REG = 0xA03;
GPO_REG = 0xA02;
GPO_0 = 0x01; //bit0 is 1
#1 : Get GPI 0 status
// Get GPI 0 Pin Status
data=ReadByte(GPI_REG); // data bit4 is GPI 0 status
#2 : Set GPO 0 status to high
// Set GPO 0 Pin to High
data=ReadByte(GPO_REG);
data |= GPO_0;
WriteByte(GPO_REG, data); //data bit0 set GPO 0 status to high
