#123578 - Same address, different circuits Responding to: ???'s previous message |
Hi Sender,
To restate what has already been said by both Russel and Andy, the memory area and the SFRs are two physically separate circuits which share common addresses. Right, that's confusing. If you access one of those addresses with direct addressing, you are accessing the SFR circuits. If you access one of those addresses with indirect addressing, you are accessing the memory circuits. Now, do you understand the difference between direct and indirect addressing? If not then this still may be a bit confusing. |
