Debug Interface and EmbeddedICE-RT
You can program one or both watchpoint units to halt the execution of instructions by
the core. Execution halts when the values programmed into EmbeddedICE-RT match
the values currently appearing on the address bus, data bus, and various control signals.
Note
You can mask any bit so that its value does not affect the comparison.
You can configure each watchpoint unit to be either a watchpoint (monitoring data
accesses) or a breakpoint (monitoring instruction fetches). Watchpoints and breakpoints
can be data-dependent in halt mode debug.
The EmbeddedICE-RT logic can be configured into a mode of operation where
watchpoints or breakpoints generate Data or Prefetch Aborts respectively. This allows
a Real-Time (RT) debug monitor system to debug the ARM while still allowing critical
fast interrupt requests to be serviced.
