6.1.2. Monitor mode

On a breakpoint or watchpoint, an Instruction Abort or Data Abort is generated instead of entering debug state in halt mode. When used in conjunction with a debug monitor program activated by the abort exception entry, it is possible to debug the processor while enabling the execution of critical interrupt service routines. The debug monitor program typically communicates with the debug host over the debug communication channel. Monitor mode debug is described in Monitor mode debug.
