8. Module: Enhanced Capture Compare
8.1 Enhanced PWM
8.2 Enhanced PWM
DS80490F-page 8
When the PWM is configured for Full-Bridge mode
and the duty cycle is set to 0%, writing the
PxM<1:0> bits to change the direction has no
effect on PxA and PxC outputs.
On the A4 revision products only, ECCP1 no
longer exhibits this problem.
Work around
Increase the duty cycle to a value greater than 0%
before changing directions.
Affected Silicon Revisions
In PWM mode, when the duty cycle is set to 0%
and the STRxSYNC bit is set, writing the STRxA,
STRxB, STRxC and the STRxD bits to enable/
disable steering to port pins has no effect on the
outputs.
Work around
Increase the duty cycle to a value greater than 0%
before enabling/disabling steering to port pins.
