constant internal and external supervision, using the watchdog timer for example. If a transition to
error-protect mode occurs, the flash memory may contain incorrect data due to errors in
programming or erasing, or it may contain data that has been insufficiently programmed or erased
because of the suspension of these operations. Boot mode should be used to recover to a normal
state.
If the memory contains overerased memory cells, boot mode may not operate correctly. This is
because the H8/3048F’s built-in boot program is located in part of flash memory, and will not read
correctly if memory cells have been overerased.

NMI input is disabled when flash memory is being programmed or erased (when the P or E bit is
set in FLMCR). NMI input is also disabled while the boot program is executing in boot mode,

NMI input is also disabled in the error-protect state while the P or E bit remains set in the flash
memory control register (FLMCR).
NMI requests should be disabled externally whenever V

NMI input during programming or erasing might cause a violation of the programming or
erasing algorithm. Normal operation could not be assured.
In the NMI exception-handling sequence during programming or erasing, the vector would not
be read correctly *
If NMI input occurred during boot program execution, the normal boot-mode sequence could
not be executed.

program is completed. After the branch to the RAM area, NMI input is enabled except
during programming or erasing. NMI interrupt requests must therefore be disabled
externally until the user program has completed initial programming (including the
vector table and the NMI interrupt-handling program).
