21.4.5 Debug Operation

When the CPU is halted in debug mode the RTC will halt normal operation. Setting the Debug Run bit in the Debug Control register (DBGCTRL.DBGRUN) forces the RTC to continue operating when the CPU is halted in debug mode.

If the RTC 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.
