Executing:
nrf_gpio_range_cfg_input(0, 39, NRF_GPIO_PIN_NOPULL);
I believe it will.
I know the range should end at 30 but I hit the wrong key when I coded it. So far, I have 2 dead DVT boards and one dead PCA10001 that not even nRFgo Studio can recover. The Segger cannot read the ARM Coresight module inside the 51822 over SWD.
I figure that if the PCA10001 is messed up I have even less hope recovering the DVT hardware.
