These bits are used to compare against the most significant byte of the
address bus.
These bits are used to compare against the least significant byte of the
address bus. These bits may be excluded from being used in the match
if BK0ALE = 0.
These bits are compared to the most significant byte of the data bus or
the most significant byte of the address bus in dual address modes.
BKEN[1:0], BKDBE, and BKMBH control how this byte will be used in the
breakpoint comparison.
