Function
Counter Idle Control:
0: Programs the PCA Counter to continue functioning during idle mode
1: Programs the PCA Counter to be gated off during idle
Watchdog Timer Enable:
0: Disables Watchdog Timer function on PCA module 4
1: Enables Watchdog Timer function on PCA module 4
Not implemented, reserved for future use.
Note: User should not write ‘1’s to reserved bits. The value read from a reserved bit is indeterminate.
PCA Count Pulse Select bit 1
PCA Count Pulse Select bit 2
PCA Enable Counter Overflow interrupt:
