#75884 - RE: Using Port2 for RAM & I/O simultaneo Responding to: ???'s previous message |
You can restrain yourself from using MOVX for several miliseconds just to get your IO work done when you have memory mapped IO and XRAM on the same ports. But what about code?
I am sure that some other "tested" ideas exist but the only way to make reliaable MMIO is to use !RD and !WR as clock/gate. Erik |
