Input/output AC characteristics
The definition and values of input/output AC characteristics are given in Figure 20 and
Table 35, respectively.
Unless otherwise specified, the parameters given in Table 35 are derived from tests
performed under ambient temperature and VDD supply voltage conditions summarized in
Table 8.
Table 35.
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.
