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 associated with unavailable pins must always keep their reset value.
3.
For a description of the DM registers, see the ST7 ICC Protocol Reference Manual. 10/108 1
