(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,
Note. XXh: PWM Duty Cycle output percentage is (XX/256*100%) during one cycle.
(2)If CPUFANOUT1 be programmed as DC Voltage output (Bank0 Index 62h.bit6 is 1)
Bit 7-2: CPUFANOUT1 voltage control.
Bit 1-0: Reserved.
Note. See the Table 6.4

Bit7 : Reserved.
Bit 6: CPUFANOUT1 output mode selection. Set to 0, CPUFANOUT1 pin is as PWM output duty
cycle so that it can drive a logical high or low signal. Set to 1, CPUFANOUT1 pin is as DC
voltage output which can provide analog voltage output. (Default 1)
CPUFANOUT1 duty cycle is 0%.
