Flags explanations:
Flags Function
M1088
Matrix comparison flag. Comparing between equivalent values (M1088 = 1) or different
values (M1088 = 0).
M1089 Matrix search end flag. When the comparison reaches the last bit, M1089 = 1.
M1090 Matrix search start flag. Comparing from bit 0 (M1090 = 1).
M1091
Matrix bit search flag. When the comparison is completed, the comparison will stop
immediately (M1091=1).
M1092 Matrix pointer error flag. When the pointer Pr exceeds its range, M1092 = 1.
