can be executed. If an unmasked interrupt request is generated in the EI state, the request branches directly from the
self-programming library to the interrupt routine. After the self-programming mode is later restored, self-programming can
be resumed. However, the interrupt response time is different from that of the normal operation mode.

The 78K0R/Lx3 microcontrollers support a self-programming function that can be used to rewrite the flash memory via
If an interrupt occurs during self-programming, self-programming can be temporarily stopped and interrupt servicing
Cautions 1. The self-programming function cannot be used when the CPU operates with the subsystem clock.
2. In the self-programming mode, call the self-programming start library (FlashStart).
3. To prohibit an interrupt during self-programming, in the same way as in the normal operation
4. In low-power-consumption mode, use the regulator with f
5. Disable DMA operation (DENn = 0) during the execution of self programming library
mode, execute the self-programming library in the state where the IE flag is cleared (0) by the DI
instruction. To enable an interrupt, clear (0) the interrupt mask flag to accept in the state where
the IE flag is set (1) by the EI instruction, and then execute the self-programming library.
