This register is read/write in all modes.
BKDBE — Enable Data Bus
Enables comparing of address or data bus values using the BRKDH/L registers.
0 = The BRKDH/L registers are not used in any comparison
1 = The BRKDH/L registers are used to compare address or data (depending upon the mode se-
lections BKEN1,0)
BKMBH — Breakpoint Mask High
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 = High byte of data bus (bits 15:8) are compared to BRKDH
1 = High byte is not used to in comparisons
BKMBL — Breakpoint Mask Low
Disables the matching of the low byte of data when in full breakpoint mode. Used in conjunction with
the BKDBE bit (which should be set)
0 = Low byte of data bus (bits 7:0) are compared to BRKDL
1 = Low byte is not used to in comparisons.
BK1RWE — R/W Compare Enable
Enables the comparison of the R/W signal to further specify what causes a match. This bit is NOT useful
in program breakpoints or in full breakpoint mode. This bit is used in conjunction with a second address
in dual address mode when BKDBE=1.
0 = R/W is not used in comparisons
1 = R/W is used in comparisons
BK1RW — R/W Compare Value
When BK1RWE = 1, this bit determines the type of bus cycle to match.
0 = A write cycle will be matched
1 = A read cycle will be matched
BK0RWE — R/W Compare Enable
Enables the comparison of the R/W signal to further specify what causes a match. This bit is not useful
in program breakpoints.
0 = R/W is not used in the comparisons
1 = R/W is used in comparisons
BK0RW — R/W Compare Value
When BK0RWE = 1, this bit determines the type of bus cycle to match on.
0 = Write cycle will be matched
1 = Read cycle will be matched
