7.5 Alternate Functions
The Alternate Function allows the pins to be
connected with the peripheral signals or NMI. Not

Port
pins
have
associated.
A Configuration Register (PORT_x_AF) for each
Port is used to switch from the Digital I/O function
or the Alternate Function.
Some pins can have two Alternate Functions: one
input function and one output function. To switch
between the two functions, the PORT_x_AF must
be configured in Alternate Function mode and the
PORT_x_DDR Configuration Register must be
switched in Input mode or in Output mode.
NMI is considered an Alternate Function. For this
reason

Alternate Function and in one of the Input modes.

Figure 7.3 Port Pin Architecture
When an on-chip peripheral is configured to use a
pin, the correct I/O mode of the related pin should
be selected by selecting one of the appropriate
modes. See the Registers description in order to
obtain the right configurations.Some peripherals,
as for example the I

C peripheral, directlydrive the
pin configuration according to the current function,
overriding the user configuration.

In order to select between the digital functions or
