PWMIF
PWM Interrupt Flag — Any change from passive to asserted (active) state or from active to passive state will be
flagged by setting the PWMIF flag = 1. The flag is cleared by writing a logic 1 to it. Writing a 0 has no effect.
0 No change on PWM5IN input.
1 Change on PWM5IN input
PWM Interrupt Enable — If interrupt is enabled an interrupt to the CPU is asserted.
0 PWM interrupt is disabled.
1 PWM interrupt is enabled.
PWM Restart — The PWM can only be restarted if the PWM channel input 5 is deasserted. After writing a logic 1
to the PWMRSTRT bit (trigger event) the PWM channels start running after the corresponding counter passes
next “counter = 0” phase.
Also, if the PWM5ENA bit is reset to 0, the PWM do not start before the counter passes 0x0000.
The bit is always read as 0.
PWM Shutdown Output Level — If active level as defined by the PWM5IN input, gets asserted all enabled PWM
channels are immediately driven to the level defined by PWMLVL.
0 PWM outputs are forced to 0
1 PWM outputs are forced to 1.
