#164867 - You generally have to set a sfr bit Responding to: ???'s previous message |
Chips with internal XRAM just use the xdata mechanism to address it. However you will probably find a XRAM bit somewhere. XRAM=0 for external XRAM=1 for internal.
I have not read your data sheet, but this is how P89C51RD2 does it. David. |
