Note:

H: High-level

L: Low-level

Hi-Z: High-impedance

Keep-O: Output pins retain their previous values. Input pins go to high-impedance.

Note 1. Input is enabled if the pin is specified as the Software Standby canceling source while it is used as an external interrupt pin.

Note 2. Input is enabled while the pin is used as an input pin.
