4.8 Peripheral Debug
The PDBG register controls the behavior of asynchronous peripherals when the device is in
debug mode.When the corresponding bit is set, that peripheral will be in a frozenstate in debug
mode.

• 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.
