BIT NAME
5 PWMF
4 CLRPWM
3-0 PWMxI
FUNCTION
12 bit counter overflow flag:
0 = The 12-bit counter is not underflow/match.
1 = The 12-bit counter is underflow/match. It will be set by hardware and cleared
by software.
1 = Clear 12-bit PWM counter to 000H. It will be automatically clear by
hardware.
0 = PWM0 output is non-inverted.
1 = PWM0 output is inverted.
Note: x = 0,2,4,6.
