breakpoint address, the emulator is using one of its eight hardware resources to
implement the breakpoint.
b
bp <program instruction>
If you suspect some kind of problem with the setting of the breakpoint, use the
analyzer to watch the setting of the breakpoint. The easiest way to do this is to
store-qualify the trace on the address where you are setting the breakpoint. The
trace list will only contain a cycle or two, but you can see what happened when the
emulator accessed the breakpoint address.
If the MMU is running, you will need to store-qualify the actual physical address
being accessed. The address given in the "bp" command must always be treated as
a logical address. To find the corresponding physical address, use the MMU
translation command. Also, keep in mind that the MMU may cause problems when
setting the breakpoint.
