ARM Cortex-A76 Core User Manual

010001 Asynchronous SError interrupt.
Note
In AArch32 the 010001 code previously meant an Asynchronous External Abort on
memory access. With the RAS extension, it extends to include any asynchronous
SError interrupt. The Parity Error codes are not used in the RAS extension.
