GPIO MODE – Select GPIO8-GPIO1 I/O mode.
0 = GPIO8-1 are programming as input pins. (Default)
1 = GPIO8-1 are programming as output pins.
BIT7 is for GPIO8 and BIT6 is for GPIO7, etc…
BIT[7:4] are reserved functions for W83795ADG.
GPIO IN – Input GPIO8-GPIO1 Data. The respective bits can be read only from pins. Write
accesses will be ignored.
BIT7 is for GPIO8 and BIT6 is for GPIO7, etc…
BIT[7:4] are reserved functions for W83795ADG.
GPIO OUT – Output GPIO8-GPIO1 Data. For output ports, it needs to set GPIO_MOD
register and the respective bits can be read/written and produced to pins.
BIT7 is for GPIO8 and BIT6 is for GPIO7, etc…
