Something else I've just noticed - not sure if this is a bug or a consequence of some hardware limitation.
Although you can set up SPI decode to frame using a clock timeout instead of needing CS, you still can't assign MOSI and MISO to different
channels, despite there being 3 inputs available, for clock, MOSI and MISO.
The fact that it displays decode lines for MISO and MOSI suggests to me that it is actually a bug. - Daniel ?
