The watchdog timer function is implemented in module 4 (See Figure 14-4).
The PCA interrupt system is shown in Figure 14-2.
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 14-3). The registers contain the
bits that control the mode that each module will operate in.
