13. Stabilization of power supply voltage
A sudden change in the supply voltage may cause the device to malfunction even within the specified VCC supply
voltage operating range. Therefore, the VCC supply voltage should be stabilized.
As a reference, stabilize the supply voltage by meeting the following standards.
VCC ripple variations (peak-to-peak value) at commercial frequencies (50 Hz/60 Hz) fall below 10
% of the
standard VCC supply voltage
The coefficient of fluctuation does not exceed 0.1 V/ms at instantaneous power switching.
14. Initialization
The device has internal registers that are only initialized by a power-on reset only. To initialize these registers,
turn on the power again.
15. Port 0 to port 3 output during power-on (external bus mode)
In external bus mode, the outputs of Port 0 to Port 3 may be indeterminate regardless of the reset input.
16. Flash security function
The security bit is located in the flash memory area. If protection code 01H is written to the security bit, the
security function is applied to the flash memory.
Therefore do not write 01H to this address if you do not use the security function.
Please refer to following table for the address of the security bit.
