#98771 - addressed 16-bit movx write Responding to: ???'s previous message |
Even adressed 16-bit movx write should be as simple as adding a 74x574 latching content of P2 on leading edge of ALE.
The write is then: mov P2,high-data mov A,low-data mov DPTR,#address movx @DPTR,Aprovided that code is executed from internal code memory. Reading is an another issue. I can be wrong, of course. Jan Waclawek |
