Size Comparator Enable Bit — The SZE bit controls whether access size comparison is enabled for the
associated comparator. This bit is ignored if the TAG bit in the same register is set.
0 Word/Byte access size is not used in comparison
1 Word/Byte access size is used in comparison
Size Comparator Value Bit — The SZ bit selects either word or byte access size in comparison for the
associated comparator. This bit is ignored if the SZE bit is cleared or if the TAG bit in the same register is set.
0 Word access size is compared
1 Byte access size is compared
