BKMBL — Breakpoint Mask Low
BK1RWE — R/W Compare Enable
BK1RW — R/W Compare Value
BK0RWE — R/W Compare Enable
BK0RW — R/W Compare Value
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)
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.
When BK1RWE = 1, this bit determines the type of bus cycle to
match.
Enables the comparison of the R/W signal to further specify what
causes a match. This bit is not useful in program breakpoints.
When BK0RWE = 1, this bit determines the type of bus cycle to match
on.
0 = Low byte of data bus (bits 7:0) are compared to BRKDL
1 = Low byte is not used in comparisons.
0 = R/W is not used in comparisons
1 = R/W is used in comparisons
0 = A write cycle will be matched
1 = A read cycle will be matched
0 = R/W is not used in the comparisons
1 = R/W is used in comparisons
0 = Write cycle will be matched
1 = Read cycle will be matched
