5.4.3
The address breakpoint low and high registers (ABLR, ABHR),
processor’s data address space that can be used as part of the trigger. These register values are compared
with the address for each transfer on the processor’s high-speed local bus. The trigger definition register
(TDR) identifies the trigger as one of three cases:
