CPUFANOUT0 PWM Input Clock Source Select. This bit selects the clock source for
PWM output.
0: The clock source is 24 MHz.
1: The clock source is 180 KHz.
CPUFANOUT0 PWM Pre-Scale divider. The clock source for PWM output is divided by
the seven-bit value to calculate the actual PWM output frequency.
PWM output frequency =
The maximum value of the divider is 127 (7Fh), and it should not be set to 0.

CPUFANOUT0 PWM Duty Cycle. The PWM duty cycle is
equal to this 8-bit value, divided by 255, times 100%. FFh
creates a duty cycle of 100%, and 00h creates a duty cycle of
0%.
