The meaning of this register is depending on the FAN2_MODE[2]:
0: the value x 16 is the fan speed count in this range.
1: the value is PWM duty-cycle (In DAC mode, the output voltage is
VCC*(SEC1SPEED2)/255) in this range.
The meaning of this register is depending on the FAN2_MODE[2]:
0: the value x 16 is the fan speed count in this range.
1: the value is PWM duty-cycle (In DAC mode, the output voltage is
VCC*(SEC2SPEED2)/255) in this range.
