user program. Because this function allows a user application to rewrite the flash memory by using a self-programming
library, it can be used to upgrade the program in the field.
can be executed. To execute interrupt servicing, restore the normal operation mode after self-programming has been
stopped, and execute the EI instruction. After the self-programming mode is later restored, self-programming can be
resumed.

The 78K0/Kx2 microcontrollers support a self-programming function that can be used to rewrite the flash memory via a
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. Oscillation of the internal high-speed oscillator is started during self programming, regardless of
3. Input a high level to the FLMD0 pin during self-programming.
4. Be sure to execute the DI instruction before starting self-programming.
5. Self-programming is also stopped by an interrupt request that is not masked even in the DI status.
the setting of the RSTOP flag (bit 0 of the internal oscillation mode register (RCM)). Oscillation of
the internal high-speed oscillator cannot be stopped even if the STOP instruction is executed.
The self-programming function checks the interrupt request flags (IF0L, IF0H, IF1L, and IF1H). If
an interrupt request is generated, self-programming is stopped.
To prevent this, mask the interrupt by using the interrupt mask flag registers (MK0L, MK0H, MK1L,
and MK1H).
