OnChip ERAM and External RAM access from C51

Steve Allen

I am using AT89C5131 uC with hardwaired external 32K RAM from address 0x0000 to 0x07fff. I am able to read/write OnChip 1K RAM and External connected RAM by toggling EXTRAM Bit in AUXR register.

I wanted to declare huge amount of varaiables in both the RAMs for my static arrays by using -at- keyword. How can I do this in ERAM?
