#133025 - 8031 memory interfacing
Hello friends,
i have struck up with this simple thing when going through 8031 memory interfacing.

When i interface a ROM (code memory) with 8031 and i wish to transfer a 8 bit data like below
Acc <- 15h
port 1 <- Acc
what instruction must be used?

eg: if i use
mov a,#15h
mov p1,a;

i wonder how this instruction could be read by the microcontroller, since it would not activate the ALE(ALE is activated only during movx and movc)

could i get some hints on it.

regard's
Suresh.
