#124244 - my best, \"the bible\" does it better Responding to: ???'s previous message |
I know Harward use 2 space of memory, one for code and other for data, but i dont understand why you repeat this all the time.
because you keep 'including' the two. CODE contains code DATA and IDATA is 'fast' data memory XDATA (EDATA is part of that) is 'slow' data memory SFR is I/O EEPROM is a peripheral (forget about it as 'memory' it IS a peripheral) you have memory all over the place address
PC | dptr | Ri | instruction
ffff code xdata
07ff edata
00ff idata SFR
0080 idata SFR
007f data
002f bdata
0020 bdata
001f registers
0000 code xdata edata data registers
This is the best that I can do, "the bible" does it so much better Erik |
