#48860 - RE: Multiplex P0 for I/O and XRAM access Responding to: ???'s previous message |
As to what Joe said, in my first failed attempt, I remember that I tried writing 0x00 or 0xFF to P0 after reading from the tri-stated buffer (74HC244) or writing to the latch (74HC573) to free up the internal bus and it still didn't work.
you MUST make logic to read/write using MOVX Erik |
