按时如何在PSoC6中复用？

你好，
现在我用PSoC6通过UART连接其他的板。董事会只有四条线，即VCC，GND，RX（GPIO）和Tx（GPIO）。该板使用TX作为GPIO唤醒PSoC6。同时，董事会使用RX作为GPIO唤醒。董事会来自其他公司，我无法修改。
是的psoc6低功耗为深睡眠。UART中断不能唤醒PSOC6从深度睡眠。因此，我希望多psoc6。
我使用P9〔0〕和P9〔1〕的PIN。
总的来说，P9 [ 0 ]配置GPIO输入。然后，董事会可以唤醒psoc6通过GPIO中断从深度睡眠。后醒来，P9 [ 0 ]需要配置UART RX从而获得董事会。
当需要发送给董事会，P9 [ 1 ]配置GPIO输出叫醒板。然后，P9 [ 1 ]需要配置UART发送，发送到板。
我想知道这种情况下是可行的吗？如何实现这一目标？
你及时的帮助将不胜感激！
谢谢，
剑轩

                                            Hi,
Now I use PSoC6 to connect other board by UART. The board only has four lines, namely, Vcc, GND, Rx(GPIO) and Tx(GPIO). The board uses Tx as GPIO to wake up PSoC6. Meanwhile, the board use Rx as GPIO to be waken up. The board is from other company, I cannot modify.

The PSoC6 is in deep sleep in order for low power consumption. UART interrupt cannot wake up PSoC6 from deep sleep. Thus, I wish to multiplex PSoC6.

I use pins of P9[0] and P9[1].

In general, P9[0] is configed as GPIO input. Then, the board can wake up PSoC6 by GPIO interrupt from deep sleep. After waked up, P9[0] need to configed as UART Rx so as to receive from the board.

When need to transmit to the board, P9[1] is configed as GPIO outpout to wake up the board. Then, P9[1] need to be configed as UART Tx so as to transmit to the board.

I want to know whether this case is feasible? How to achieve the goal?

Your timely support would be highly appreciated!

Thanks,

Jianxuan
