The auto-erasing is sus-
pended and the interrupt pro-
cess is executed. The auto-
erasing can be restarted by
setting the FMR41 bit in the
FMR4 register to “0” (erase
restart) after the interrupt
process completes
The auto-erasing has a prior-
ity and the interrupt request
acknowledgement is waited.
The interrupt process is ex-
ecuted after the auto-erasing
completes
The auto-programming has a
priority and the interrupt re-
quest acknowledgement is
waited. The interrupt process
is executed after the auto-
programming completes
When maskable interrupt
request is acknowledged
Once an interrupt request is acknowledged,
the auto-programming or auto-erasing is forc-
ibly stopped and resets the flash memory. An
interrupt process starts after the fixed period
and the flash memory restarts. Since the block
during the auto-erasing or the address during
the auto-programming is forcibly stopped, the
normal value may not be read. Execute the
auto-erasing again and ensure the auto-eras-
ing is competed normally. Since the watchdog
timer does not stop during the command op-
eration, the interrupt request may be gener-
ated. Reset the watchdog timer regularly using
the erase-suspend function.
