2.9.3.4. Setting Data Breakpoints.
It is possible to define breakpoints when a read and / or write of a particular address
occurs. This is enabled by selecting the « R » option for read and the « W » option
for write in the watch table. It is also possible to add a logical relationship to this data
breakpoint (for example break only when 0F is written to the address location). To
define a relation select the « Rel » or « Match » option and enter the relationship.
The following relationships are possible.
Data breakpoint evaluation is only active if the data breakpoint enable button is
selected in the « Execution Toolbar» of the Emulator control window.
Relationship
<>= MATCH Always true ( break)
<= MATCH
>= MATCH
<>MATCH
< MATCH
> MATCH
