Re: 1571/1581 Sources: Macro WDTEST inserting NOP before reading WD177x status register / writing command register

If your thought is true, then isn't that a justifiable cost tradeoff?

My initial thought was that there was some speed issue accessing the
chip and the macro was written based on a guess that happened to work.

Unless you prove what the issue is, then you can't tell whether the
address bits are important or it just randomly works if you insert nops
based on that heuristic.
