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.
