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.
These bits are compared to the least significant byte of the data bus or the least significant byte of the
address bus in dual address modes. BKEN[1:0], BKDBE, BK1ALE, and BKMBL control how this byte
will be used in the breakpoint comparison.
