A.10 Exception flags signals
DEFLAGS and SCUEVABORT signals are the Exception flag signals.
Table A-24 Exception flags signals
|DEFLAGSn[6:0]||O||System integrity controller||
Data Engine output flags. Only implemented if the Cortex®‑A9 processor includes a Data Engine.
If the DE is NEON SIMD unit:
If the DE is FPU:
|SCUEVABORT||O||Indicates an external abort has occurred during a coherency writeback. SCUEVABORT is a pulse signal that is asserted for one CLK clock cycle.|
