- 'DATA': <data1> contains the MISO data, <data2> contains the MOSI data.
The data is _usually_ 8 bits (but can also be fewer or more bits).
Both data items are Python numbers (not strings), or None if the respective
- probe was not supplied.
+ channel was not supplied.
- 'BITS': <data1>/<data2> contain a list of bit values in this MISO/MOSI data
item, and for each of those also their respective start-/endsample numbers.
- 'CS CHANGE': <data1> is the old CS# pin value, <data2> is the new value.
