Note:

Supply current is the total current flowing into VCC and VRTC. Supply current values are with all output pins unloaded and all input

pull-up MOSs in the off state.

Note:

This does not include the BGO operation.

Note:

The clock source is LOCO.

Note 1. PCLKA, PCLKB, PCLKC, and PCLKD are set to divided by 64 (512 Hz).

Note:

Supply current values do not include output charge/discharge current from all pins. The values apply when internal pull-up MOS

transistors are in the off state. Supply current is the total current flowing into VCC and VRTC.

Note:

The IWDT and LVD are not operating.

Note:

If you want to operate RTC, add the value of Table 2.15.

Note:

Supply current values do not include output charge/discharge current from all pins. The values apply when internal pull-up MOS

transistors are in the off state. The supply current is total current flowing into VRTC.
