DVP-ES2/EX2/EC5/SS2/SA2/SX2/SE&TP Operation Manual - Programming
Program Example:
When X0 goes from OFF to ON with M1090 = OFF (comparison starts from Pr), the search will
start from the bit marked with “*” (current Pr value +1) for the bits with different status (M1088 =
OFF).
Assume pointer D20 = 2, the following four results (, , , ) can be obtained when X0 goes
from OFF→ON for four times.
D20 = 5, M1091 = ON (matched result found), M1089 = OFF
D20 = 45, M1091 = ON, M1089 = OFF.
D20 = 47, M1091 = OFF, M1089 = ON (comparison proceeds to he last bit)
D20 = 1, M1091 = ON, = OFF.

Points to note:
Associated flags and registers:
M1088:
Matrix comparison. Comparing between equivalent values (M1088 = ON) or different
values (M1088 = OFF)
D1089: Indicating the end of Matrix. When the comparison reaches the last bit, M1089 = ON
D1090:
Indicating start of Matrix comparison. When the comparison starts from the first bit,
M1090 = ON
D1091:
Indicating matrix searching results. When the comparison has matched results,
comparison will stop immediately and M1091 = ON
D1092:
Indicating pointer error. When the pointer Pr exceeds the comparison range, M1092 =
ON.
