BK1RW — R/W Compare Value
BK0RWE — R/W Compare Enable
BK0RW — R/W Compare Value
These bits are used to compare against the most significant byte of the
address bus.
Table 63 Breakpoint Read/Write Control
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.
