Note 1: Design and set constants according to the crystal oscillator to be connected.
Note 2: The power supply/memory hold current is the value obtained by summing the XVDD and MVDD pin currents.
Note 3: The values are those when the power supply detector function is operating. Setting the function reduces
current dissipation by 150 A (typ.). (Except in Standby mode)
An asterisk (*) indicates the values are guaranteed when VDD
