ROBO-8713BVG2 GPIO Programming Guide
There are 8 GPIO pins on ROBO-8713BVG2. These GPIO pins are from SUPER I/O
(W83627HF) GPIO pins, and can be programmed as Input or Output direction.
J25 pin header is for 8 GPIO pins and its pin assignment as following :
J25_Pin1=GPIO1:from SUPER I/O_GPIO10 with Ext. 4.7K PH
J25_Pin2=GPIO2:from SUPER I/O_GPIO11 with Ext. 4.7K PH
J25_Pin3=GPIO3:from SUPER I/O_GPIO12 with Ext. 4.7K PH
J25_Pin4=GPIO4:from SUPER I/O_GPIO13 with Ext. 4.7K PH
J25_Pin6=GPIO5:from SUPER I/O_GPIO14 with Ext. 4.7K PH
J25_Pin7=GPIO6:from SUPER I/O_GPIO15 with Ext. 4.7K PH
J25_Pin8=GPIO7:from SUPER I/O_GPIO16 with Ext. 4.7K PH
J25_Pin9=GPIO8:from SUPER I/O_GPIO17 with Ext. 4.7K PH
<<<<< Be careful Pin5=GND , Pin10=VCC >>>>>
There are several Configuration Registers (CR) of W83627HF needed to be
programmed to control the GPIO direction, and status(GPI)/value(GPO). CR00h ~
CR2F are common (global) registers to all Logical Devices (LD) in W83627HF.
CR07h contains the Logical Device Number that can be changed to access the LD as
needed. LD7 contains the GPIO10~17 registers.
