    Hello,

    • SPSR_ABT holds the value of the CPSR before the abort exception occurs.
    • R13_ABT is the pointer to the top of the stack in CPU memory used by the abort handler
    • R14_ABT is the address of the Program Counter (PC) which points to the instruction that caused the abort + 8 bytes (due to CPU pipeline)

    For more details on exception handling, please refer to the ARM v7A/R Architecture Reference Manual, ARM literature number DDI0406C.

    Regards,

    Sunil
