The register is meaningful when CPUFANOUT1 be programmed as PWM output.
Bit 7: CPUFANOUT1 PWM Input Clock Source Select. This bit selects the clock source of PWM
Bit 6-0: CPUFANOUT1 PWM Pre-Scale divider. This is the divider of clock source of PWM output
the formula is
6.8.57 CPUFANOUT1 Output Value Select Register - Index 61h (Bank 0)

Size:
(1)If CPUFANOUT1 be programmed as PWM output (Bank0 Index 62h.bit6 is 0)
Bit 7-0: CPUFANOUT1 PWM Duty Cycle. Write FFh, CPUFANOUT1 duty cycle is 100%. Write 00h,
output frequency.
Set to 0, select 24 MHz.
Set to 1, select 180 KHz.
frequency. The maximum divider is 128 (7Fh). This divider should not be set to 0.
CPUFANOUT1 duty cycle is 0%.
01h : divider is 1
