servicing can be executed. To execute interrupt servicing, restore the normal operation mode after self-programming
has been stopped, and execute the EI instruction.

The 78K0/LC3 supports a self-programming function that can be used to rewrite the flash memory via a user
If an interrupt occurs during self-programming, self-programming can be temporarily stopped and interrupt
Cautions 1. The self-programming function cannot be used when the CPU operates with the subsystem
Because this function allows a user application to rewrite the flash memory by using the 78K0/LC3 self-
2. Input a high level to the FLMD0 pin during self-programming.
3. Be sure to execute the DI instruction before starting self-programming.
4. Self-programming is also stopped by an interrupt request that is not masked even in the DI
clock.
The self-programming function checks the interrupt request flags (IF0L, IF0H, IF1L, and IF1H).
If an interrupt request is generated, self-programming is stopped.
status. To prevent this, mask the interrupt by using the interrupt mask flag registers (MK0L,
MK0H, MK1L, and MK1H).
