The register is meaningful only when SYSFANOUT is programmed for PWM output (
Bank0 Index 04h, bit 0 is 0).
Bit 7: SYSFANOUT PWM Input Clock Source Select. This bit selects the clock source for PWM output
Bit 6-0: SYSFANOUT PWM Pre-Scale divider. The clock source for PWM output is divided by this
The maximum value of the divider is 127 (7Fh), and it should not be set to 0.
