Appendix 1. Port States in Each Processing Mode
Keep-O: Output pins retain their previous values, and input pins become high-impedance.
Hi-Z: High-impedance
Note 1. Input is enabled if the pin is specified as the software standby mode canceling source while it is used as an external interrupt pin.
Note 2. Input is enabled if the pin is used a USB pin (USB0_VBUS/USB0_OVRCURA/USB0_OVRCURB).
