BK0ALE — Breakpoint 0 Range Control
This register is read/write in all modes.
BKDBE — Enable Data Bus
BKMBH — Breakpoint Mask High
BK1ALE BK0ALE
Valid in all modes.
Enables comparing of address or data bus values using the BRKDH/L
registers.
Disables the comparing of the high byte of data when in full breakpoint
mode. Used in conjunction with the BKDBE bit (which should be set)

0 = BRKAL will not be used to compare to the address bus.
1 = BRKAL will be used to compare to the address bus.
0 = The BRKDH/L registers are not used in any comparison
1 = The BRKDH/L registers are used to compare address or data
0 = High byte of data bus (bits 15:8) are compared to BRKDH
1 = High byte is not used to in comparisons
