W79E825A/824A/823B/822B Data Sheet
BIT NAME
FUNCTION
0: The PWM is not running.
7 PWMRUN
1: The PWM counter is running.
6 Load
0: The registers value of PWMP and PWMn are never loaded to counter and
Comparator registers.
1: The PWMP and PWMn registers load value to counter and compare registers
at the counter underflow. This bit is auto cleared by hardware at next clock
cycle.
5 CF
0: The 10-bit counter down count is not underflow.
1: The 10-bit counter down count is underflow. This bit is Software clear.
4 CLRPWM 1: Clear 10-bit PWM counter to 000H. This bit is auto cleared by hardware.
3 PWM3I
0: PWM3 out is non-inverted.
1: PWM3 output is inverted.
2 PWM2I
0: PWM2 out is non-inverted.
1: PWM2 output is inverted.
1 PWM1I
0: PWM1 out is non-inverted.
1: PWM1 output is inverted.
0 PWM0I
0: PWM0 out is non-inverted.
1: PWM0 output is inverted.
