-2.6.5 Data Abort
-There are three Abort Model in ARM arch.
-
-Early Abort Model: used in some ARMv3 and earlier implementations. In this
-model, base register wirteback occurred for LDC,LDM,STC,STM instructions, and
-the base register was unchanged for all other instructions. (oldest)
-
-Base Restored Abort Model: If a Data Abort occurs in an instruction which
-specifies base register writeback, the value in the base register is
-unchanged. (strongarm, xscale)
-
-Base Updated Abort Model: If a Data Abort occurs in an instruction which
-specifies base register writeback, the base register writeback still occurs.

-2.4 Register1:control register
-L(bit 6): in some ARMv3 and earlier implementations, the abort model of the
-processor could be configured:
-0=early Abort Model Selected(now obsolete)
-1=Late Abort Model selceted(same as Base Updated Abort Model)
-
-on later processors, this bit reads as 1 and ignores writes.
--------------------------------------------------------------
-So, if lateabtSig=1, then it means Late Abort Model(Base Updated Abort Model)
