Talk:Status flags

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.
