SYSFANOUT Value
(1)If SYSFANOUT be programmed as PWM output (CR[F0h] of LD B bit4 is 1)
Bit 7-0: SYSFANOUT PWM Duty Cycle. Write FFh, SYSFANOUT is always logical High which means
duty cycle is 100%. Write 00h, SYSFANOUT is always logical Low which means duty cycle is
0%.
Note. XXh: PWM Duty Cycle output percentage is (XX/255*100%) during one cycle.
(2)If SYSFANOUT be programmed as DC Voltage output (CR[F0h] of LD B bit4 is 0)
Bit 7-4: SYSFANOUT voltage control.
Bit 3-0: Reserved.
OUTPUT Voltage = AVCC * ^FANOUT
