DESCRIPTION
GPIO8 Output Value. GPIO8 output value if EN_GPIO8
is set to 1. Write 1, then pin 8 (GPIO8) always generate
logic high signal. Write 0, pin 8 (GPIO8) always generates
logic low signal. This bit default 0.
Enable GPIO8 Function. Which enable multiple function
pin 8, named OVT#/GPIO8, GPIO8 function. Set to 0
(default), pin 8 (OVT#/GPIO8) acts as OVT#. Set to 1,
this pin 8 acts as GPIO8 control function and the output
value of GPIO8 is programmed by this register bit 7.
GPIO7 Output Value. GPIO7 output value if EN_GPIO7
is set to 1. Write 1, then pin 7 (GPIO7) always generate
logic high signal. Write 0, pin 7 (GPIO7) always generates
logic low signal. This bit default 0.
