CPUFANOUT0 Value
(1)If CPUFANOUT0 be programmed as PWM output (Bank0 Index 04h.bit1 is 0)
Bit 7-0: CPUFANOUT0 PWM Duty Cycle. Write FFh, CPUFANOUT0 duty cycle is 100%. Write 00h,
CPUFANOUT duty cycle is 0%.
Note. XXh: PWM Duty Cycle output percentage is (XX/256*100%) during one cycle.
(2)If CPUFANOUT0 be programmed as DC Voltage output (Bank0 Index 04h.bit1 is 1)
Bit 7-2: CPUFANOUT0 voltage control.
Bit 1-0: Reserved.
OUTPUT Voltage =
