PWMOUT1 duty cycle. This register is programmable at Manual
mode. At SPEED or TEMPERATURE mode, this register reflects
current PWMOUT duty-cycle.
While PIN4 is set to PWMOUT mode, the PWMOUT2 will output full
duty cycle (FFh) to enable system FAN. After 10 seconds when
detecting FANIN1 signal, assuming the fan has been fully turned
on, the fan speed count detected will be recorded in the register. If
there is no signal on FANIN2 after power on, the PWMOUT2 will
keep outputting FFh duty cycle.
