I'm a newbie, and I wanted to poll the community to see if there is any collateral describing or explaining the use of the PSoC3 (or 5L) SPI interface with frames less than 8 bits? I haven't checked the PSoC creator yet, so maybe it's outlined there. I'm just getting started, but l'm looking forward to it.
Welcome in the forum!
The SPI component for PSoC3 or 5LP works with 3- to 16bit transfers. I suggest you to install Creator and look at the datasheet for all the features of all the components..
