Notes:

1. The contents of the I/O port DR registers are readable only in output configuration. In input configura-

tion, the values of the I/O pins are returned instead of the DR register contents.

2. The bits corresponding to unavailable pins are forced to 1 by hardware, affecting accordingly the reset

status value. These bits must always keep their reset value.

3. External pin not available.
