W83627DHG
(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
255, times 100%. FFh creates a duty cycle of 100%, and 00h creates a duty cycle of 0%.
(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.
OUTPUT Voltage = AVCC * ^FANOUT
