MB90340E Series

11.4.2 Reset Standby Input

(TA  40°C to 105°C, VCC  5.0 V  10, fCP 24 MHz, VSS  AVSS  0.0 V)

* : The oscillation time of the oscillator is the time it takes for the amplitude of the oscillations to reach 90

. For

crystal oscillators, this time is between several ms and several tens of ms, for ceramic oscillators the time is

between several hundred

s and several ms, and for an external clock, the time is 0 ms.
