I'm confused about the issue with using GPOPTE inputs in low power applications. errata 97 indicates that GPIOTE should not be used in input mode
It was also discussed on the Here in the Forum with regards to the nRF51.
However, the forum indicates that the app_button library has the work around in it. I still see the app_button library configuring the GOIPTE as inputs in the 13.1 SDK
err_code = nrf_drv_gpiote_in_init(p_btn->pin_no, &config, gpiote_event_handler);
What function is it that needs to be avoided in low current applications?
