Hi, I'm reading the nRF5340 OPS v0.5.1 document and in section 3.2 ("Memory") there is a reference to "256kB of peripheral RAM". However, the document doesn't explain what "peripheral RAM" means in this context. I get that the "single-cycle RAM" region is a region that's faster for the CPU to use, but what about the "peripheral RAM"? Are there any restrictions on this RAM region (or on the "single-cycle RAM" region for that matter) for general application use? Thank you.
