'''
SPI(-like) protocols with a clock line, a MISO and MOSI line for data
transfer in two directions, and an optional CS# pin.
+Either MISO or MOSI (but not both) can be optional.
+
If CS# is supplied, data is only decoded when CS# is asserted (clock
transitions where CS# is not asserted are ignored). If CS# is not supplied,
data is decoded on every clock transition (depending on SPI mode).
