Section 23 Flash Memory
23.10
23.10.1 Prohibited Interrupts (EW0 Mode)
• The NMI and watchdog timer interrupts can be used because FLMCR1 is forcibly initialized
23.10.2 Access Method
To set the FMCMDEN bit to 1, be sure to write 0 to the bit and then write 1 in a row. Make sure
that no interrupt, EXDMAC transfer, DTC transfer, or DMA transfer is generated between writing
0 and 1.
23.10.3 Programming (EW0 Mode)
If the power-supply voltage falls during programming of the block that stores the programming
control program, the programming control program cannot be correctly modified and the flash
memory may not be programmed after that. In this case, use the on-board programming mode or
programmer mode instead.
23.10.4 Writing Commands or Data
The address to write a command code should be a multiple of four (H'0, H'4, H'8, H'C, ...).
23.10.5 Software Standby Mode
Before entering the stop mode, set the FMCMDEN bit to 0 (CPU programming mode disabled),
disable the DMA transfer, and then make a transition to the software standby mode.

when an interrupt is generated; specify the destination address of each interrupt routine in the
fixed vector table. Flash memory programming is terminated when an NMI interrupt or a
watchdog timer interrupt occurs. In this case, execute the programming program again after the
interrupt routine is completed.
