This register defines interrupt masking and the output behavior for the
associated PWM channel.
PGEx is used to start and stop the PWM script execution.
PWMENx sets the PWM output to either reflect the generated pattern
or the value configured in PWMPOLx.
Mask for CDIRQx
0: CDIRQx enabled
1: CDIRQx disabled/masked
Pattern Generator Enable. Start/Stop PWM command processing for
this channel. Script execution is started always from beginning.
0: Pattern Generator disabled
1: Pattern Generator enabled
0: PWM disabled. PWM timer output assumes value programmed in
PWMPOL.
1: PWM enabled
Off-state of PWM output, when PWMEN=0.
0: PWM off-state is low
1: PWM off-state is high
Reset control on all PWM timers
A reset forces the pattern generator to fetch the first pattern and stops
it. Each reset stops all state-machines and timer.
Patterns stored in the pattern configuration register remain unaffected.
Interrupts on each timer are not cleared, they need to be cleared
writing into register TIMIC
(reserved)
Software reset of timer 2.
0: no action
1: Software reset on timer 2, needs not to be written back to 0.
Software reset of timer 1.
0: no action
1: Software reset on timer 1, needs not to be written back to 0.
Software reset of timer 0.
0: no action
1: software reset on timer 0, needs not to be written back to 0.
