Notes:
1. X = Don’t Care (no functional difference for individual module if 1 or 0).
2. A = Enable interrupts for this module (PCA interrupt triggered on CCFn set to 1).
3. B = Enable 8th, 9th, 10th or 11th bit overflow interrupt (Depends on setting of CLSEL[1:0]).
4. C = When set to 0, the digital comparator is off. For high speed and frequency output modes, the
5. D = Selects whether the Capture/Compare register (0) or the Auto-Reload register (1) for the associated
6. E = When set, a match event will cause the CCFn flag for the associated channel to be set.
7. All modules set to 8, 9, 10 or 11-bit PWM mode use the same cycle length setting.
associated pin will not toggle. In any of the PWM modes, this generates a 0% duty cycle (output = 0).
channel is accessed via addresses PCA0CPHn and PCA0CPLn.
