Notes

Unless otherwise specified by a note, all I/Os are set as floating inputs

during and after reset.

Pin functions

Alternate functions

Functions selected through GPIOx_AFR registers

Additional functions

Functions directly selected/enabled through peripheral registers

1. Refer to SYSCFG_CCCSR register in the device reference manual for how to set a group of I/Os in High-speed low-voltage mode.

Depending on the chosen I/Os (for example OCTOSPI), it can belong to several groups of I/Os and several HSLVx bits need to be set (refer

to Table Pin/ball definition). Take care that the VDDIO_HSLV and/or VDDMMC_HSLV option bits must also be set.

2. Refer to the table Features and peripheral counts for the list of packages featuring a VDDMMC separate supply pad.
