Alternate function remapping

As shown in the rightmost column of Table 11, 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 9: Option bytes on page 54. 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 STM8S series and STM8AF series 8-bit microcontrollers reference manual,

RM0016).
