(1)If CPUFANOUT1 is programmed for PWM output (Bank0 Index 62h, bit 6 is 0)
Bit 7-0: CPUFANOUT1 PWM Duty Cycle.The PWM duty cycle is equal to this eight-bit value, divided by
(2)If CPUFANOUT1 is programmed for DC output (Bank0 Index 62h, bit 6 is 1)
Bit 7-2: CPUFANOUT1 voltage control.The output voltage is calculated according to this equation.
Bit 1-0: Reserved.
