#99540 - I`m confused with A15 Responding to: ???'s previous message |
hi,
Jan Waclawek said:
/CS connected to P2.7 (A15);
This should map the memory to addresses 8000h-FFFFh in both external data and code memory space; No, it does not. Because /CS is activated with low level so such schematic maps memory into addresses 0000h-7FFFh. Regards, Oleg |
