9 This sample shows how to use in Zephyr nRF peripherals that share the same ID
11 share certain hardware resources, but it is possible to switch between them and
15 this sample uses the nrfx drivers directly for those peripheral instances that
18 Zephyr console and SPIM1 is used for performing additional sample transfers).
20 The sample uses two buttons:
21 - by pressing Button 1 user can request a transfer to be performed using the
23 - by pressing Button 2 user can switch between the two peripherals
28 The sample outputs on the standard console the hex codes of all sent and
35 on the boards supported by the sample are assigned as MOSI/MISO and TX/RX pins.
