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 XV_DD and MV_DD pin currents.
Note 3: The values are those when the power supply detector function is operating. Setting the function reduces
current dissipation by 150 mA (typ.). (Except in Standby mode)
An asterisk (*) indicates the values are guaranteed when V_DD = MV_DD = XV_DD = DV_DD = AV_DD and Ta = -40 to
85°C.
When CD is off, V_DD = DV_DD = AV_DD = 0 V
