Table 89. Output AC characteristics, HSLV OFF (all I/Os except FT_o I/Os and PC13)

FT_o I/O characteristics are provided in Table 91.

The I/O structure options listed in this table can be a concatenation of options including the option explicitly listed. For instance, TT_a refers to

any TT I/O with _a option. TT_xx refers to any TT I/O and FT_xx refers to any FT I/O.

The I/O speed is configured using the OSPEEDRy[1:0] bits. Refer to the product reference manual for a description of GPIO port configuration

Specified by design. Not tested in production.
