+ * Corrupted Return PC in Exception Stack Frame
+ * When processing an autovectored interrupt an error can occur that

+ * exception stack frame. The problem is caused by a conflict between
+ * an internal autovector access and a chip select mapped to the IACK
+ * address space (0xFFFFXXXX).
+ * Workaround:
+ * Set the C/I bit in the chip select mask register (CSMR) for the
+ * chip select that is mapped to 0xFFFFXXXX.
+ * This will prevent the chip select from asserting for IACK accesses.
