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.

Recommended Oscillation Circuit and Characteristics
The oscillation circuit characteristics in the table below are based on the following conditions:
* Recommended
circuit parameters are verified by an oscillator manufacturer using a Sanyo provided oscillation evaluation
board.
* The
characteristics are the results of the evaluation with the recommended circuit parameters connected externally.

For further assistance, please contact with the oscillator
Since the oscillation frequency precision is affected by wiring capacity of the application board, etc., adjust the oscillation frequency on the production board.
Since the oscillation circuit characteristics are affected by the noise, wiring capacity, etc., refer to the following notices. * The distance between the clock I/O terminal and external parts should be as short as possible. * The capacitors' VSS should be allocated close to the microcontroller's GND terminal and be away from other GND. * The signal lines with rapid state changes or the signal line with large amplitude such as middle withstand voltage port or LCD driver output should be allocated away from the clock oscillation circuit. * The signal lines with large current should be allocated away from the oscillation circuit.
