#69282 - Just ignore me - Im talking rubbish!
Responding to: ???'s previous message
Andrew Ayre said:
#include <reg51.h>
:
:
DPL = 0x05; // access 8051 SFR
DPH = 0x12;


I said:
Shouldn't that be:
sfr DPL = 0x..;
sfr DPH = 0x..;


Sorry; ignore that - Andrew was completely correct!

The SFR definitions are contained in the reg51.h header file - so once you've #included it, you can use the SFRs like any other 'C' variable!

Of course, this still does NOT make it a good idea!
