17.5.5 Debug Operation

When the CPU is halted in debug mode, the SYSCTRL continues normal operation. If the SYSCTRL is configured in a way that requires it to be periodically serviced by the CPU through interrupts or similar, improper operation or data loss may result during debugging.

If debugger cold-plugging is detected by the system, BOD33 reset will be masked. The BOD resets keep running under hot-plugging. This allows to correct a BOD33 user level too high for the available supply.
