nRF52832 WLCSP - read pin SWDIO

[John Waters]

I am on project using nRF52832 WLCSP.

What's the pin assignment for SWDIO pin? I want to read the input of SWDIO (as indicated in datasheet it's Digital I/O) and can it be read using nrf_gpio_pin_read() ?

My objectif is to know if there is a short-circuit in this pin. So my code to read will be temporary.

Thanks,
John

Hi,

I agree that the documentation is a bit ambiguous on this part. But this pin can not be read by the application as a normal GPIO with the GPIO drivers. You would have to physically measure on the pad to check if it's shorted.
