Breakpoint Mask High Byte for First Address — In dual or full mode, these bits may be used to mask (disable)
the comparison of the high and/or low bytes of the first address breakpoint. The functionality is as given in

The x:0 case is for a full address compare. When a program page is selected, the full address compare will be
based on bits for a 20-bit compare. The registers used for the compare are {DBGCAX[5:0], DBGCAH[5:0],
DBGCAL[7:0]}, where DBGAX[5:0] corresponds to PPAGE[5:0] or extended address bits [19:14] and CPU
address [13:0]. When a program page is not selected, the full address compare will be based on bits for a 16-bit
compare. The registers used for the compare are {DBGCAH[7:0], DBGCAL[7:0]} which corresponds to CPU
address [15:0].
Note: This extended address compare scheme causes an aliasing problem in BKP mode in which several
The 1:0 case is not sensible because it would ignore the high order address and compare the low order and
expansion addresses. Logic forces this case to compare all address lines (effectively ignoring the BKAMBH
control bit).
The 1:1 case is useful for triggering a breakpoint on any access to a particular expansion page. This only makes
sense if a program page is being accessed so that the breakpoint trigger will occur only if DBGCAX compares.
Breakpoint Mask High Byte and Low Byte of Data (Second Address) — In dual mode, these bits may be
used to mask (disable) the comparison of the high and/or low bytes of the second address breakpoint. The

Read/Write Comparator A Enable Bit — The RWAEN bit controls whether read or write comparison is enabled
for comparator A. See
for tagged operations.
0 Read/Write is not used in comparison
1 Read/Write is used in comparison
Read/Write Comparator A Value Bit — The RWA bit controls whether read or write is used in compare for
comparator A. The RWA bit is not used if RWAEN = 0.
0 Write cycle will be matched
1 Read cycle will be matched
