The GPIO& WDT are using internal Super IO function. However, you must entry
super I/O configuration mode to set it.
The output port is set as GPIO 1 on CN13, reg. index = 0x60
The input port is set as GPIO 4 on CN12, reg. index = 0x62.
Super I/O special address port = 0x2E
Super I/O special data port = 0x2F
GPIO Logical device is 0x07
