acknowledged
Once an interrupt request is acknowledged, the auto-
programming or auto-erasing is forcibly stoped 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-eras-
ing again and ensure the auto-erasing is completed
normally.
Since the watchdog timer does not stop during the
command operation, the interrupt request may be
generated. Reset the watchdogi timer regularly.
