six breakpoints, two with Context ID comparison capability, BRP4 and BRP5. See Breakpoint Value Registers and Breakpoint Control Registers.

four watchpoints.

A watchpoint event is always synchronous. It has the same behavior as a synchronous data abort. The method of debug entry (DBGDSCR[5:2]) never has the value b0010.

If a synchronous abort occurs on a watchpointed access, the synchronous abort takes priority over the watchpoint.

If the abort is asynchronous and cannot be associated with the access, the exception that is taken is unpredictable.

Cache maintenance operations do not generate watchpoint events
