The SFR area is between 0x80 and 0xFF, also the Upper RAM area is between 0x80 and 0xFF. I can access the SFR using direct addressing and the Upper RAM using indirect addressing. My question: are the SFR and Upper RAM physically 2 different memorys? If I use all of the SFR registers can I also use the Upper RAM memory (both have the same address area)? (overwrite data) data crash? Thanks
Shh. Don't bring up pdata. That's our little secret :-). - Mark
The next thing I know, you guys will be talking about SMALL memory model and moving big variables and buffers into XDATA. Jon
