You can say its a part of Internal RAM. Sure, you can say it - but you'd be wrong. For just one example, consider SBUF: Writing to SBUF does not write to any sort of RAM - it writes to the UART's transmitter register; Reading from SBUF does not read from any sort of RAM - it reads from the UART's receiver register. The OP needs to know where the SFRs are physically located?? . I feel they are not located on the Plastic die of the MCU :) . 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 . " SFRs are accessed as if they were normal Internal RAM. 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. " Best/ AP |
