Legend: x=undefined, R/W=read/write
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.
