STM8串口是不是可以重映射用不同的引脚进行分时复用。

我看资料引脚介绍上面有两个串口1的口，求解释。

1. When the

A1/NRST pin is used as general purpose (PA1), it can be configured only as output push-pull, not as a general
purpose input. Refer to Section Configuring NRST/PA1 pin as general purpose output in the STM8L15x reference manual
(RM0031).
2. Available on STM8L152xx devices only.
3. [ ] Alternate function remapping option (if the same alternate function is shown twice, it indicates an exclusive choice not a
duplication of the function).
4. In the open-drain output column, ‘T’ defines a true open-drain I/O (P-buffer and protection diode to VDD are not implemented).
5. Available on STM8L151xx devices only.
6. High Sink LED driver capability available on

A0.

看了，但是在选项字页面也没有串口的重映射。
