Pinouts and pin description
Table 6.
1. The default state of UART1_RX and UART3_RX pins is controlled by the ROM bootloader. These pins are pulled up as
2. The beCAN interface is available on STM8S208xx devices only
3. In the open-drain output column, ‘T’ defines a true open-drain I/O (P-buffer, weak pull-up, and protection diode to V
4. The PD1 pin is in input pull-up during the reset phase and after the internal reset release.
5. Available in 44-pin package only. On other packages, the AFR4 bit is reserved and must be kept at 0.

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
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).
