The register is meaningful when CPUFANOUT0 be programmed as PWM output.
Bit 7: CPUFANOUT0 PWM Input Clock Source Select. This bit selects the clock source of PWM
Bit 6-0: CPUFANOUT0 PWM 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.
the formula is
