Output Modes
The output configuration is selected by setting the
corresponding DDR register bit. In this case, writ-
ing the DR register applies this digital value to the
I/O pin through the latch. Then reading the DR reg-
ister returns the previously stored value.
Two different output modes can be selected by
software through the OR register: Output push-pull
and open-drain.
DR register value and output pin status:
Note: When switching from input to output mode,
the DR register has to be written first to drive the
correct level on the pin as soon as the port is con-
figured as an output.

10.2.2 Alternate Functions
When an on-chip peripheral is configured to use a
pin, the alternate function is automatically select-
ed. This alternate function takes priority over the
standard I/O programming under the following
conditions:
– When the signal is coming from an on-chip pe-
– When the signal is going to an on-chip peripher-

output mode (push-pull or open drain according
to the peripheral).

mode. In this case, the pin state is also digitally
readable by addressing the DR register.
