I wonder exactly how many sram cells there are in a 51 MCU core.
The data sheet says overlapped 128 upper ram with address 80H~FFH accessed by INDIRECT addressing, while these address space accessed by DIRECT addressing should be SFRs.
So I really puzzled about the Internal RAM and SFRs are exactly uses the same storage cells.
Any help will be appreciate!!
