The auto repair labor rates vary by location, your vehicle's make and model, and even … 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.
