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 Nop this is not the Question he asks in the first place.

SFRs are part of internal SRAM. is it true?... Regarding the word "plastic Die" I mean plastic die package , and not silicon , I know semiconductors are made out of silicon. 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 Oh my God, who says ? SFRs are connected to the internal SRAM . Ap Charles said:

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 That means the address must be pointing to heaven! Please read the content again it says " The only difference is that Internal RAM is from address 00h through 7Fh whereas SFR registers exist in the address range of 80h through FFh." |
