The following is a sample code for 8 in (DIO 0-7) 8 out (DIO 8-15, 4
low 4 high)
Outportb(0x2E,0x87); //enter configuration
Outportb(0x2E,0x87);
Outportb(0x2E,0x07); //set LDN
Outportb(0x2F,0x06);
Outportb(0x2E,0x88); //GPIO set 8 register
Outportb(0x2F,0x00); //Set GPIO8x (DIO 0-7) as input mode
Outportb(0x2E,0x80); //GPIO set 7 register
Outportb(0x2F,0xFF); //Set GPIO7x (DIO 8-15) as output mode
Outportb(0x2E,0x81); //GPIO output data register
Outportb(0x2F,0xF0); //DIO 8-11 as Low, DIO 9-15 as high
Outportb(0x2E,0xAA); //exit configuration
