I'm using the CYBL10563 and I'm wondering if it is possible to change the UART Tx/Rx pin to digital pins? What I wanted to do exactly was
- Enable UART.
- When the device goes to sleep, disable UART and configure Tx as an output and Rx as an input.
- Read a pulse on Rx to wakeup.
- Once awake from sleep mode, re-enable the UART.
Is it possible do this and switch between these two modes for the pins?
Any ideas would be great!
