If the reset pulse applied to the external reset pin (RST) does not meet the specifications, it may cause
malfunctions. Use caution so that the reset pulse less than the specifications will not be fed to the external
reset pin (RST) .

Note : Be sure that the power supply will come on within the selected oscillator stabilization period. Also, when
varying the supply voltage during operation, it is recommended that the supply voltage be increased gradually.
