This register indicates the LSB of the FAN1 full speed count. This register can
be auto update by hardware or program by user. If user programming this
register before hardware, then the hardware will not update this register again.
Return 0 when read.
Expect fan speed count value or expect PWM duty , in auto fan mode this
register is auto updated by hardware and read only.
This register reflects current PWMOUT2 duty-cycle.
Return 0 when read.
GPIO3 output control. Set to 1 for output function. Set to 0 for input function
(default).
GPIO2 output control. Set to 1 for output function. Set to 0 for input function
(default).
GPIO1 output control. Set to 1 for output function. Set to 0 for input function
(default).
GPIO0 output control. Set to 1 for output function. Set to 0 for input function
(default).
Expect fan speed count value or expect PWM duty , in auto fan mode this
register is auto updated by hardware and read only.
