execution of the control program, copy the control program into the RAM area or obtain it from the external using
the communication pin. The procedures to execute the control program in the RAM area in the MCU mode are
described below.
In the MCU mode, write operations are performed by executing the control program in the RAM area. Before

Note 1: Before writing to the flash memory in the RAM area, disable interrupts by setting the interrupt master
Note 2: When writing to the flash memory, do not intentionally use non-maskable interrupts (the watchdog timer

How to write to the flash memory by executing a user write control program in the RAM area (in
1. Transfer the write control program to the RAM area.
2. Jump to the RAM area.
3. Disable (DI) the interrupt master enable flag (IMF←"0").
4. Disable the watchdog timer, if it is used.
5. Set FLSCR<FLSMD> to "0011B" (to enable command sequence execution).
6. Execute the erase command sequence.
7. Read the same flash memory address twice.
8. Execute the write command sequence.
9. Read the same flash memory address twice.
10. Set FLSCR<FLSMD> to "1100B" (to disable command sequence execution).
11. Jump to the flash memory area.

must be disabled if it is used). If a non-maskable interrupt occurs while the flash memory is being written,
unexpected data is read from the flash memory (interrupt vector), resulting in malfunction of the micro-
controller.
(Repeat step 7 until the same data is read by two consecutive read operations.)
(Repeat step 9 until the same data is read by two consecutive read operations.)
