STM32WL - SUBGHZSPI DEBUG

For a project of mine, I wanted a LoRa Transceiver like (like the SX1262) to be controlled by a host application running on a STM32F4. I have a few STM32WLE5CCU6s lying around from a previous project, and was thinking if I could use them instead.

 

The SX1262 drivers are written in the host application, so I just need to access the actual transceiver's SPI and other signal lines.

 

I realize that the DEBUG option exposes critical pins like the SPI, NSS, RESET and BUSY. But are the DEBUG lines writeable or are they just for monitoring of signals?

Hello @MoralkaraLynn 

Radio is controlled internally through SUBGHZSPI and, for debug purpose only, from the external. So, the exposed options are used only for Debug.
