The OP needs to know where the SFRs are physically located?? No, that is not the question he asked. The question he asked was: Koosha Khannakhjavani said:
I mean internal SRAM which is used as internal data memory. The answer to that question is, most definitely that no location anywhere in the internal SRAM is accessed by accessing an SFR So the answer to the question: Koosha Khannakhjavani said:
SFRs are part of internal SRAM. is it true? Is: No, that is false The SFRs are not part of the internal SRAM. They may be addressed in a similar way to the internal SRAM, but they are not in any way part of the internal SRAM. Koosha Khannakhjavani said:
I know thay are part of data memory space, but I want to know if they are part of SRAM? Yes, they are addressed in the same address space - but they are not part of the internal SRAM. Ap Charles said:
I feel they are not located on the Plastic die of the MCU The die is not plastic - it is silicon! Ap Charles said:
I give the link here : http://www.8052.com/tutsfr.phtml
All the locations for SFR are correctly mentioned in the table for internal RAM. No - that table shows the SFR address space - it does not show the internal RAM Ap Charles said:
"SFRs are accessed as if they were normal Internal RAM..." Note my emphasis there: the similarity with internal RAM is purely in the way they are addressed - the SFRs themselves are not in any way connected to the internal SRAM, as the original question asked |
