Bit0:
Note: When the WDTE bit is set to ‘1’, the PCA0MD register cannot be modified. To change the

Bit7
contents of the PCA0MD register, the Watchdog Timer must first be disabled.
CIDL: PCA Counter/Timer Idle Control.
Specifies PCA behavior when CPU is in Idle Mode.
0: PCA continues to function normally while the system controller is in Idle Mode.
1: PCA operation is suspended while the system controller is in Idle Mode.
WDTE: Watchdog Timer Enable
If this bit is set, PCA Module 5 is used as the watchdog timer.
0: Watchdog Timer disabled.
1: PCA Module 5 enabled as Watchdog Timer.
WDLCK: Watchdog Timer Lock
This bit locks/unlocks the Watchdog Timer Enable. When WDLCK is set, the Watchdog
Timer may not be disabled until the next system reset.
0: Watchdog Timer Enable unlocked.
1: Watchdog Timer Enable locked.
UNUSED. Read = 0b, Write = don't care.
These bits select the timebase source for the PCA counter
ECF: PCA Counter/Timer Overflow Interrupt Enable.
This bit sets the masking of the PCA Counter/Timer Overflow (CF) interrupt.
0: Disable the CF interrupt.
1: Enable a PCA Counter/Timer Overflow interrupt request when CF (PCA0CN.7) is set.
*Note: External clock divided by 8 and smaRTClock clock divided by 8 are synchronized with the
