Note
The microcontroller will malfunction if the power supply voltage is less than the specified operable supply voltage. To
prevent a malfunction, the low voltage detect circuit should be connected externally, and the voltage should always be set
to the proper level. If the power supply voltage becomes lower than the voltage which is detected by the low voltage detect
reset IC, then the microcontroller should be reset to restore stable operation. Use the low voltage detect reset IC which
detects the lowest specification voltage of the power supply.
We cannot ensure the integrity of the block data, if the microcontroller is reset while writing to the flash memory.
Therefore, in such a case, we recommend disabling any flash writing operation by user's program when the voltage
decreases to a level just above the voltage which is detected by the low voltage detect reset IC.
