'''
|

|
|
The SPI (Serial Peripheral Interface) 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.
|
||
|
|
|
||
|
|
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).
