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