 		 #29375 - RE: HOW TO ACCESS 512K OF EXTERNAL MEMORY
And remaing 3 address lines (A16,A17,A17) controlling by 74HC573 latch
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.
