1. The I/O speed is configured using the OSPEEDRx[1:0] bits. Refer to the RM0091 reference manual for a description of
GPIO Port configuration register.
2. The maximum frequency is defined in
3. Guaranteed by design, not tested in production.
4. The I/O speed configuration is bypassed in FM+ I/O mode. Refer to the STM32F05xxx reference manual RM0091 for a
description of FM+ I/O mode configuration.
