Description
PM DataEvents
Enables PM data breakpoints.PM data breakpoints are similar to data
breakpoints (Data page), except accesses that trigger a PM breakpoint are
made by DAG2 or the PM() modifier. Like data breakpoints, PM data
breakpoints cause a break on accesses to internal memory, IOP registers,
the external port (EP), and multiprocessor memory space (MMS).
I/O
Enables IO breakpoints.IO breakpoints are triggered by accesses made on
the IO Address Bus. Use an IO breakpoint to break on accesses made dur-
ing DMA transfers, MMS accesses, and Host accesses.
