i first of all thans Neil to make my figure clear and understandable to anyone.
I will go through the "external mempory interface on p1 of Chapter 1, and p6 of Chapter 3." and then see.
I will also gothrough interrupts described on p18 of Chapter 3.
1) Which microcontroller? - DALLAS DS89C430----This micro has
only /R and /W lines. No /IOR or /IOW is present.
2) Look at the signals that are on your microcontroller,
and work out how to use them to activate the UART's /IOR
and /IOW lines.????????????
It should be possible using SIMPLE LOGIC GATES??????
HOW to do that i can get. What signls to use along with
/R and /W to convert them into /IOR and /IOW.
