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 VCC.

Note:

The IWDT and LVD are not operating.

Note:

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