#98670 - MMIO?
Responding to: ???'s previous message
So i want to allocate BFA9H to Refresh ....
And then read/write from/to this 16 bit location
Now what is the best approach for this allocation?


This has an inherent problem as do all 16 bit MMIO cases. You must find a way to handle atomicity (usually only possible with a (C)PLD/FPGA)

It is MMIO (Memory mMapped I/O) or, if not why the absolute addresses?
