Input/output AC characteristics
The definition and values of input/output AC characteristics are given in Figure 23 and
Table 59, respectively.
Unless otherwise specified, the parameters given in Table 59 are derived from tests
performed under ambient temperature and VDD supply voltage conditions summarized in
Table 23.

1. The I/O speed is configured using the OSPEEDRx[1:0] bits. Refer to the line reference manual for a description of GPIO Port
configuration register.
2. Guaranteed by design.
3. The maximum frequency is defined in Figure 23.
4. When Fm+ configuration is set, the I/O speed control is bypassed. Refer to the line reference manual for a detailed
description of Fm+ I/O configuration.
