1. 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.

2. 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 register.
