Pinouts and pin descriptions

5.3

Alternate function remapping

As shown in the rightmost column of the pin description table, some alternate functions can

be remapped at different I/O ports by programming one of eight AFR (alternate function

remap) option bits. Refer to Section 8: Option bytes. When the remapping option is active,

the default alternate function is no longer available.

To use an alternate function, the corresponding peripheral must be enabled in the peripheral

registers.

Alternate function remapping does not effect GPIO capabilities of the I/O ports (see the

GPIO section of the family reference manual, RM0016).
