+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)
