SYSFANOUT Output Value Select Register - Index 01h (Bank 0)
SYSFANOUT PWM Input Clock Source Select. This bit selects the clock source for
PWM output frequency.
0: The clock source is 24 MHz.
1: The clock source is 180 KHz.
SYSFANOUT PWM Pre-Scale divider. The clock source for 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.

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%.
