On STM8 controller the 4-pin SWIM interface has a power pin (pin#1) that has been indicated to sense the target voltage. Can this pin be repurposed some way to drive the target board ? So SWIM interface provides output power so the target circuitry d...

For example how can the IO pins be set for alternate function mapping to non-default pin. As per datasheet same alternate pin function is mapped to multiple pins. For example USART1_TX is shown to be available on PC3 and also PA2. By programming all ...
