The other description on CPU ALL is pretty good, but I wanted to present the flags in a way that conceptually makes clear that in the processor, they are just 6 separate flags with no ordering in a byte, and that it's when they're copied to a byte in memory that the other two bits of the byte are given values. I tried to emphasize that the memory version is a copy, which conceptually avoids one thinking of the copy as the actual flags. --Blargg 08:37, 5 November 2010
- So can you think of some way to divide the description between Status flags and CPU status flag behavior so that things aren't unnecessarily covered twice? --Tepples 16:44, 5 November 2010 (UTC)
- I don't understand the distinction between six flags that are copied in a certain order and there being a byte somewhere on the chip with the flags ordered that way. As far as I can tell, the two concepts are entirely equivalent. - furrykef 21:53, 21 March 2011 (UTC)
