PEVC

AST

• WDT: Watchdog PDBG bit

WDT = 0: The WDT counter is not frozen during debug operation.

WDT = 1: The WDT counter is frozen during debug operation when Core is halted

• AST: Asynchronous Timer PDBG bit

AST = 0: The AST prescaler and counter is not frozen during debug operation.

AST = 1: The AST prescaler and counter is frozen during debug operation when Core is halted.

• PEVC: PEVC PDBG bit

PEVC= 0: PEVC is not frozen during debug operation.

PEVC= 1: PEVC is frozen during debug operation when Core is halted.
