+'''
+Serial Peripheral Interface protocol decoder.
+
+This protocol decoder supports synchronous SPI(-like) protocols with a
+clock line, a MISO and MOSI line for data transfer in two directions,
+and an optional CS# pin.
+
+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).
