CPUFANOUT Value
(1)If CPUFANOUT be programmed as PWM output (CR[F0h] of LD B bit5 is 1)
Bit 7-0: CPUFANOUT PWM Duty Cycle. Write FFh, CPUFANOUT duty cycle is 100%. Write 00h,
CPUFANOUT duty cycle is 0%.
Note. XXh: PWM Duty Cycle output percentage is (XX/255*100%) during one cycle.
(2)If CPUFANOUT be programmed as DC Voltage output (CR[F0h] of LD B bit5 is 0)
Bit 7-4: CPUFANOUT voltage control.
Bit 3-0: Reserved.
OUTPUT Voltage = AVCC * ^FANOUT
