Defining the Conditions for Analysis
The events selected cause the debugger to halt the processor whenever the
occurrence of a call taken, a branch taken, a pipeline clock, the EMU0 pin
being driven low, or a program or data bus being accessed is detected.
If you want to enable a hardware breakpoint at a particular program or data
address, you can enter the address as a symbol or value in any format.
Setting up the event comparators
The analysis module has separate event comparators for the program and
data buses. You can set up analysis to either count the number of accesses
to a certain bus address or halt the processor on accesses to a specified
address.
The program and data bus fields in the Analysis break events dialog box are
identical to the program and data bus fields in the Analysis count events dialog
box. As a result, changing the values in these fields in either dialog box affects
both of these dialog boxes.
The program bus supports noninstruction read and write accesses and
instruction fetches. If you enable the Access qualifier, noninstruction reads
and writes are detected. If you enable the Fetch qualifier, only program fetches
are detected.
Similarly, if you select Data Bus, load the data address field with 0x0800 and
select Access in the Analysis break events dialog box, the processor halts
every time a read or write occurs on the data bus at address 0x0800:
Break when a read
or write occurs at
address 0x0800 on
the data bus.
Look for read
or writes.
Enabling one of the program or data bus comparators in the Analysis count
events dialog box allows you to count the number of accesses that are detected or to stop processing after a certain number of accesses have occurred.
