The register is only meaningful when CPUFANOUT1 is programmed for PWM output.
Bit 7: CPUFANOUT1 PWM Input Clock Source Select. This bit selects the clock source for PWM
Bit 6-0: CPUFANOUT1 PWM Pre-Scale divider. The clock source of PWM output is divided by this
The maximum value of the divider is 127 (7Fh), and it should not be set to 0.
