In which state are the configured UART pins if the device is held in RESET for nRF52832? We want to use the UART to communicate with the host without the nRF52832 in certain cases.
Also, if the device is unpowered, can the UART be used with the host (not using nRF52832 of course), or will this likely damage the device as it will exceed the Abs.Max rating for I/O pins, V_I/O < VDD+0.3V?
