GPIO7 Data/Status Register. Write this bit, the data will
response to GPIO7, set to output mode. If read this register, will
return this pin data that can input or output in this pin.
GPIO6 Data/Status Register. Write this bit, the data will
response to GPIO6, set to output mode. If read this register, will
return this pin data that can input or output in this pin.
GPIO5 Data/Status Register. Write this bit, the data will
response to GPIO5, set to output mode. If read this register, will
return this pin data that can input or output in this pin.
GPIO4 Data/Status Register. Write this bit, the data will
response to GPIO4, set to output mode. If read this register, will
return this pin data that can input or output in this pin.
GPIO3 Data/Status Register. Write this bit, the data will
response to GPIO3, set to output mode. If read this register, will
return this pin data that can input or output in this pin.
GPIO2 Data/Status Register. Write this bit, the data will
response to GPIO2, set to output mode. If read this register, will
return this pin data that can input or output in this pin.
GPIO1 Data/Status Register. Write this bit, the data will
response to GPIO1, set to output mode. If read this register, will
return this pin data that can input or output in this pin.
GPIO0 Data/Status Register. Write this bit, the data will
response to GPIO0, set to output mode. If read this register, will
return this pin data that can input or output in this pin.
Reserved.
Set to 1, pin 43 will serve as a general purpose I/O, GPIO10 is
stand along with other GPIO pin.
Write ‘1’ means programmed VID output value as you wish.
Default is ‘0’.
Note: Programmed VID must be carefully, it may cause
CPU damaged.
Set to 0, FAN4/5, PWM4/5 pin switch to GPIO6-GPIO9. Set to
1 is FAN4/5 and PWM4/5. Default is 1.
