SPI: where to define how many bit DATA?

Postby sapote » Tue Aug 23, 2016 9:36 pm

Sorry if I miss the obvious, but I had tried a few times and unable to find where to define the number of bits for the SPI protocol. I wanted to have 9bit data and the tool defaulted 8bit.

Thanks,
Brian

I found this post on forum for software version 6.10.11.15, see link below. It shows the SPI Protocol Setting with number of data bits per word Field. Why the latest version 6.11.12.1692 no longer has this data bit field? SPI is not only for 8bit data width, and many devices have 12bit words, and without be able to assign the data width, then how the tooldecodes 12bit word protocol correctly?
