Module Description
The FPB also contains six instruction comparators for
matching against instruction fetches from Code space, and
remapping to a corresponding area in System space.
Alternatively, the six instruction comparators can individually
configure the comparators to return a Breakpoint Instruction
(BKPT) to the processor core on a match, so providing
hardware breakpoint capability.
TPIU (Trace Port Inteface Unit) Asynchronous Mode (1-pin) = TRACE_SWO (available on
JTAG_TDO)
