Considering using LPC MCUs for a project.
Need to interface to devices with 20-bit SPI frames, which is very common (for 20-bit ADCs, DACs, etc); for example:
Note in particular the CS requirements in the either datasheet above (CS must be held low for 20-bit duration).
There many other 20-bit SPI parts with similar requirements.
I had a quick read of the LPC176x SSP description here: https://www.nxp.com/docs/en/user-guide/UM10360.pdf
I can't see how one does a transfer longer than 16 bits (which is supported for example on Kinetis SPI).
How does one do a 20-bit SPI transfer?
Does this apply across all LPC family devices or do some have different SPI capabilities?
Thanks in advance,
Best Regards, Dave
