than one peripheral chip select may be activated at a time, and more than one peripheral chip can be connected
to each PCS pin, provided proper fanout is observed. PCS0 shares a pin with the slave select (SS) signal, which
initiates slave mode serial transfer. If SS is taken low when the QSPI is in master mode, a mode fault occurs.
