 		 #29374 - RE: HOW TO ACCESS 512K OF EXTERNAL MEMORY
8051 is the micon (89C51) what i am using.
and my programme is as follows..
i am not addressing 24 bits by DPTR..
addressing only 16 bits by DPTR.
And remaing 3 address lines (A16,A17,A17) controlling by 74HC573 latch.
putting the higher byte (A16,A17,A17) on latch and incrementing the 16 address bits by DPTR..
so the previous instruction what i gave is right...
till now i am not using any MX series..
so tell me what is the extact process if i want to use MX series..
is possible or not without MX series accessing of memory..
regrads
