For RAM locations, I've looked at the getting started guide that discusses using debugging to find the RAM address. https://devzone.nordicsemi.com/nordic/short-range-guides...
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...
Hi Sir,
As check the ref. schematic of CKAA, the pin count shows 94.
But in the below table shows the pin count is 93
Is there a typo in the datasheet (V1.1)?
