CPUFANOUT0 Value
(1)If CPUFANOUT0 is programmed for PWM output (Bank0 Index 04h,bit1 is 0)
Bit 7-0: CPUFANOUT0 PWM Duty Cycle. The PWM duty cycle is equal to this eight-bit value, divided
by 255, times 100%. FFh creates a duty cycle of 100%, and 00h creates a duty cycle of 0%
(2)If CPUFANOUT0 is programmed for DC Voltage output (Bank0 Index 04h,bit1 is 1)
Bit 7-2: CPUFANOUT0 voltage control. The output voltage is calculated according to this equation.
OUTPUT Voltage = AVCC * ^FANOUT
64
Bit 1-0: Reserved.
