23.11 Programmer Mode
In programmer mode, the on-chip flash memory can be programmed/erased by a PROM
programmer via a socket adapter, just like for a discrete flash memory. Use a PROM programmer
that supports the Hitachi 64/128/256-kbyte flash memory on-chip MCU device*. Figure 23.13
shows a memory map in programmer mode.
Note: For 3-V and 5-V version products, set the programming voltage of the PROM programmer
to 3.3V.

23.12 Usage Notes
The following lists notes on the use of on-board programming modes and programmer mode.
1. Perform programming/erasing with the specified voltage and timing.
If a voltage higher than the rated voltage is applied, the product may be fatally damaged. For
3-V and 5-V version products, use a PROM programmer that supports the Hitachi 64/128/256-
kbyte flash memory on-chip MCU device at 3.3 V. Do not set the programmer to HN28F101
or the programming voltage to 5.0 V.
2. Notes on power on/off
At powering on or off the Vcc power supply, fix the 5(6 pin to low and set the flash memory
to hardware protection state. This power on/off timing must also be satisfied at a power-off and
power-on caused by a power failure and other factors.
3. Perform flash memory programming/erasing in accordance with the recommended algorithm
