Note 1. This is the value when low driving ability is selected in the Port Drive Capability bit in the PmnPFS register. The selected driving

ability is retained in Deep Software Standby mode.

Note 2. This is the value when middle driving ability is selected in the Port Drive Capability bit in the PmnPFS register. The selected driving

ability is retained in Deep Software Standby mode.

Note 3. This is the value when high driving ability is selected in the Port Drive Capability bit in the PmnPFS register. The selected driving

ability is retained in Deep Software Standby mode.

Note 4. SCL0_D, SDA0_D (total 2 pins). This is the value when IIC function is selected.

Note 5. Except for P000 to P003, P200, which is an input port.

Caution: To protect the reliability of the MCU, the output current values should not exceed the values in this table.

The average output current indicates the average value of current measured during 100 µs.
