7.8.1
PCA capture mode
To use one of the PCA modules in the capture mode (
Figure 23
) either one or both of
the CCAPM bits CAPN and CAPP for that module must be set. The external CEX
input for the module (on port 1) is sampled for a transition. When a valid transition
occurs the PCA hardware loads the value of the PCA counter registers (CH and CL)
into the module’s capture registers (CCAPnL and CCAPnH).
3
MATn
Match. When MATn = 1 a match of the PCA counter with this
module’s compare/capture register causes the CCFn bit in CCON
to be set, flagging an interrupt.
Toggle. When TOGn = 1, a match of the PCA counter with this
module’s compare/capture register causes the CEXn pin to toggle.
Pulse Width Modulation Mode. PWMn = 1 enables the CEXn pin to
be used as a pulse width modulated output.
Enable CCF Interrupt. Enables compare/capture flag CCFn in the
CCON register to generate an interrupt.
