LLWU Pin Configuration

I do not plan on using wake-up functionality in my application.  Are there any special considerations I should be aware of if I would like to use (for example) the PTE1/LLWU_P0 pin for general purpose IO?  Is this even possible?

Thank you.

As long as the PTE1 is not configured as a wakeup source by enabling the corresponding bit in LLWU Pin Enable 1 Register (LLWU_PE1_WUPE0), you can use it as a GPIO.

Actually, I believe you can use the GPIO functionality and the LLWU functionality at the same time.
