Note:

Hi-Z: High-impedance

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

Keep-I: Pin states are retained the same as during periods in Normal mode.

Keep: Pin states are retained the same as during periods in Software Standby mode.

Note 1. Retains the I/O port state until the DPSBYCR.IOKEEP bit is cleared to 0.

Note 2. Input is enabled if the pin is specified as the Software Standby canceling source while it is used as an external interrupt pin.

Note 3. Input is enabled if the pin is specified as the Deep Software Standby canceling source.

Note 4. Input is enabled while the pin is used as an input pin.

Note 5. For host operation, set the USBHS.SYSCFG.DRPD bit to 1 to enable the USBHS_DP and USBHS_DM pull-down resistors.

For device operation, set the USBHS.SYSCFG.DPRPU bit to 1 to enable the DP pull-up resistor.

Note 6. Input is enabled if the PDMIF sound detection interrupt is specified as the Software Standby canceling source.
