PCA Modules: each one of the five compare/capture modules has six possible functions. It can
perform:
In addition, module 4 can be used as a Watchdog Timer.
Each module in the PCA has a special function register associated with it. These registers are:
CCAPM0 for module 0, CCAPM1 for module 1, etc. (See Table 6-6). The registers contain the
bits that control the mode that each module will operate in.
• 16-bit Capture, positive-edge triggered,
• 16-bit Capture, negative-edge triggered,
• 16-bit Capture, both positive and negative-edge triggered,
• 16-bit Software Timer,
• 16-bit High Speed Output,
• 8-bit Pulse Width Modulator.
• The ECCF bit (CCAPMn.0 where n=0, 1, 2, 3, or 4 depending on the module) enables the
• PWM (CCAPMn.1) enables the pulse width modulation mode.
• The TOG bit (CCAPMn.2) when set causes the CEX output associated with the module to

capture input will be active on. The CAPN bit enables the negative edge, and the CAPP bit
enables the positive edge. If both bits are set both edges will be enabled and a capture will
occur for either transition.
