 		 #29478 - RE: HOW TO ACCESS 512K OF EXTERNAL MEMORY
it would be easier to help you if you answered questions, so again:
What drives the latch (P1.0, P1.1, P1.2?)

There is NO instruction movx @dptr,#..

Does micon mean microcontroller ?

Is the 89C51 a f89C51pqx from acme or what, just 89C51 does not specify the derivative fully.

what is rhe clock speed?

what memory chips are you using (FULL type, please)

Erik
