MAGPIO as inputs

okwestern

I would like to use MAGPIO0, 1 and 2 as 1.8V inputs. I've read through the documentation, but can't find any way to assign pin numbers to these (I'm using Zephyr), only that they are general 1.8V I/Os. Is it possible to read these inputs, and better yet, attach interrupts to them? I can only find info about controlling LNA/RF switches etc. with them.

    Hi,

    The pins are reserved for the modem. Not available for the application.

    Thanks for the answer - as I feared (prototype is already assembled).

    I revised the schematics and now added control of the BGA524N6 (GNSS LNA... COEX0 connected to "power on control" (pin 6)). Before it was tied high. Would this be a wise connection?

    Hi,

    Without seeing your design I would think that this a correct connection. This would be similar as we have done on the nRF91 DK where we have connected COEX0 to the Enable pin on the FEM:
