22 The SPI (Serial Peripheral Interface) protocol decoder supports synchronous
23 SPI(-like) protocols with a clock line, a MISO and MOSI line for data
24 transfer in two directions, and an optional CS# pin.
26 If CS# is supplied, data is only decoded when CS# is asserted (clock
27 transitions where CS# is not asserted are ignored). If CS# is not supplied,
28 data is decoded on every clock transition (depending on SPI mode).
