Working with the ADF7021 in 4FSK mode, there's an errata sheet out that shows SWD does not work with 4FSK and the ADF7021, and my own experimentation has shown that to be true. The errata sheet for the ADF7021-N, however, doesn't have this problem listed. Is it accurate that the ADF7021-N properly uses the SWD line in 4FSK mode, or is it simply an omission from the errata sheet? I'll be working with the chip in an existing design to see, but wanted to find out if there's an official answer before I put a lot of effort into it.
