nRF52832 SPI module does not support hardware control of DCX signal

[moose]

I know one of nRF52840 SPI instances supports direct DCX signal drive but I can't seem to find any mention to this feature in nRF52832 so I am assuming none of its instances can support it. This post is to confirm our understanding before we drive it manually. Thx!

This is only SPIM3 to have such DCX.  Thus, you need to use the nrfx_spim driver.

SPIM3 is only available on nRF52840 and not nRF52832

Yes, you are right.  nRF52832 doesn't have the DCX pin.
