The nRF52832 documentation has sections both for SPIM/SPIS (SPI peripheral using EasyDMA) and SPI (raw, direct write to the TXD register).
Indeed the nRF52832 does support such a manual SPI access, even though the section 48 is mentioned as "legacy support".
But the nRF52810 documentation doesn't mention direct access (and the associated registers) at all.
Do nRF52810 and nRF52840 still support this direct SPI access w/o EasyDMA?
I am prototyping on nRF52832, but the final product would rather use nRF52810.
NRF52810 does not have legacy SPI.
NRF52840 has legacy SPI.
If you have NRF52832 DK (PC10040) you can emulate with some minor limitations NRF52810. You can find more details here:
