Input/output AC characteristics
The definition and values of input/output AC characteristics are given in Figure 24 and
Table 36, respectively.
Unless otherwise specified, the parameters given in Table 36 are derived from tests
performed under the ambient temperature and VDD supply voltage conditions summarized
in Table 9.
Table 36.
I/O AC characteristics(1)
1.
The I/O speed is configured using the MODEx[1:0] bits. Refer to the STM32F10xxx reference manual for a
description of GPIO Port configuration register.
