Bit 6-0: AUXFANOUT PWM Pre-Scale divider. This is the divider of clock source of PWM output
the formula is
6.8.20 AUXFANOUT Output Value Select Register - Index 11h (Bank 0)

Power on Default Value:
Attribute:
Size:
(1)If AUXFANOUT be programmed as PWM output (Bank0 Index 12h.bit0 is 0)
Bit 7-0: AUXFANOUT PWM Duty Cycle. Write FFh, AUXFANOUT duty cycle is 100%. Write 00h,
Note. XXh: PWM Duty Cycle output percentage is (XX/256*100%) during one cycle.
(2)If AUXFANOUT be programmed as DC Voltage output (Bank0 Index 12h.bit0 is 1)
Bit 7-2: AUXFANOUT voltage control.
Bit 1-0: Reserved.
Note. See the Table 6.4
frequency. The maximum divider is 128 (7Fh). This divider should not be set to 0.
AUXFANOUT duty cycle is 0%.
01h : divider is 1
02h : divider is 2
