Hi Team,
Recently, I am developing spi functions. There is a function that makes me confused --"nrfx_is_in_ram".
I am not clear that what types belong to RAM data. ...
The datasheet for the nRF52840 states, in section 5.3.6.7, what retained registers do and then, rather unhelpfully, states that details can be found in individual peripheral...
