Bit 7: FANPWM1 Clock Source Select. This bit selects the clock source of FANPWM1 output
frequency.
Set to 0, select 24 MHz.
Set to 1, select 180 KHz.
Bit 6-1: FANPWM1 Pre-Scale divider. This is the divider of clock source of PWM output frequency. The
maximum divider is 128 (7Fh). This divider should not be set to 0.
