- * See ARM Architecture Reference Manual ch. B4.9.6 (pdf p.743).
+ * "VMSAv6 added a fifth fault status bit (bit[10]) to both the IFSR and DFSR.
+ * It is IMPLEMENTATION DEFINED how this bit is encoded in earlier versions of
+ * the architecture. A write flag (bit[11] of the DFSR) has also been
+ * introduced."
