Connecting nrf21540 to a nrf52840. 840 GPIO default state is input, input buffer connected. One of the 840 GPIO pins is connected to the 540 PDN pin.
1) If the 840 gets stuck in the bootloader before the GPIO to the 540 PDN pin is configured, what state will the 540 PDN pin be in? Clarifying, the 840 GPIO pin will not be driving the 540 PDN pin.
2) If the 840 resets while its GPIO is driving the 540 PDN pin high (so the 840 will no longer be driving the 540 PDN pin), will the 540 PDN pin drift low, disabling the 540?
Thanks,
Bob
