PWM_CLK_SEL4. CPUFANOUT1 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.
PWM_SCALE4. CPUFANOUT1 PWM Pre-Scale Divider. The clock source of PWM
output is divided by this 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.

CPUFANOUT1 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 creates a duty cycle of 0%.
