The FLASHCALW interrupt request lines are connected to the NVIC. Using the FLASHCALW
interrupts requires that it is programmed first.
14.4.4
Debug Operation
When an external debugger forces the CPU into debug mode, the FLASHCALW continues nor-
mal operation. If the FLASHCALW 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.
