#148089 - Don\'t think memory, think SFR ! Responding to: ???'s previous message |
The idea of clearing a bit that is already zero doesn't make any sense to me,
It does not make much sense for bit-adressable data memory. However, there are also bit-adressable SFRs, where a write access may have side effects, or that have bits that might suddenly be set to 1 by a peripheral. |
