10.5.2. Asynchronous aborts

The processor ensures that all possible outstanding asynchronous data aborts are recognized before entry to the debug state. The debug asynchronous aborts discarded bit, DBGDSCR.ADAdiscard, is set to 1 on entry to debug state.

While in debug state with DBGDSCR.ADAdiscard set, asynchronous data aborts generated as a result of double bit ECC errors are not discarded. This is because the processor cannot determine whether the abort was generated from the debugger or from external system activity.

While in debug state with DBGDSCR.ADAdiscard set, the Cortex-A15 processor reports AXI bus errors by asserting nAXIERRIRQ or nINTERRIRQ pin.
