WebDec 14, 2024 · If you have some 16bit mask, then you can write the low 16bits to BSRR; take a complement and write it to BRR. You don't have to do any shifting. It probably maps to the same logic (flip-flop/whatever), so BSRR (16..32) is the same as BRR (0..15) but no need to shift things. Both are atomic safe as they are one to write. http://www.iotword.com/7818.html
