GPIO
The ROBO-8712E series provides 8 programmable input or output ports that can be
individually configured to perform a simple basic I/O function. Users can configure
each individual port to become an input or output port by programming register bit
of I/O Selection. To invert port value, the setting of Inversion Register has to be
made. Port values can be set to read or write through Data Register.

Programming Guide
There are 8 GPIO pins on ROBO-8712E series. These GPIO pins are from SUPER I/O
(W83627HF) GPIO pins, and can be programmed as Input or Output direction.
J5 pin header is for 8 GPIO pins and its pin assignment as following:
J5_Pin1=GPIO1: from SUPER I/O_GPIO10 with Ext. 4.7K PH
J5_Pin2=GPIO2: from SUPER I/O_GPIO11 with Ext. 4.7K PH
J5_Pin3=GPIO3: from SUPER I/O_GPIO12 with Ext. 4.7K PH
J5_Pin4=GPIO4: from SUPER I/O_GPIO13 with Ext. 4.7K PH
J5_Pin6=GPIO5: from SUPER I/O_GPIO14 with Ext. 4.7K PH
J5_Pin7=GPIO6: from SUPER I/O_GPIO15 with Ext. 4.7K PH
J5_Pin8=GPIO7: from SUPER I/O_GPIO16 with Ext. 4.7K PH
J5_Pin9=GPIO8: from SUPER I/O_GPIO17 with Ext. 4.7K PH
