All interrupts, including NMI input, are disabled when flash memory is being programmed or

For these reasons, in on-board programming mode alone there are conditions for disabling
interrupts, as an exception to the general rule. However, this provision does not guarantee normal
erasing and programming or MCU operation. All interrupt requests, including NMI, must
therefore be restricted inside and outside the MCU when programming or erasing flash memory.
The NMI interrupt is also disabled in the error-protection state while the P or E bit remains set in
FLMCR1.
