Use MOVX commands, used to place data on DATA Bus.
The MOVX data does NOT stay on P0. When the execution of a movx is complete, the port revert to P0 data. Thus, you must use (decoded) !RD and !WE signals to strobe your LCD. If, however you use P0 data as the source, you can use P1 pins if you follow what I stated above. Then you do not have to diasble the external RAM. Erik |
