∗4 The current consumption in power saving mode does not include the VREF pin output current. When

grounding the VREF pin to the AGND2 level using external resistance, a voltage of 1.18 to 1.32V is

generated at the VREF pin even in power saving mode. Therefore, the current indicated by the following

equation flows from the AVCC2 pin to the VREF pin. This value must be added to obtain the actual current

consumption in power saving mode.
