BIT NAME
FUNCTION
7
PWMRUN
0 = The PWM is not running.
1 = The PWM counter is running.
6 Load
This bit is auto cleared by hardware after the PWMP and PWMn are transferred
to counter and compare register:
0 = The registers value of PWMP and PWMn is never loaded to counter and
compare registers.
1 = The PWMP and PWMn registers load value to counter and compare
registers at the counter underflow/match.
5 PWMF
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.
4
CLRPWM
1 = Clear 12-bit PWM counter to 000H. It will be automatically clear by
hardware.
3-0 PWMxI
0 = PWM0 output is non-inverted.
1 = PWM0 output is inverted.
Note: x = 0,2,4,6.
