DM0002
Writes the C001 current
value into DM0001.
Writes the C002 current
value into DM0002.
Writes the C003 current
value into DM0003.
Application of MUL instruction
■ Multiplying the counter current value by DM value
Multiplies the counter current value by the DM0000 value and writes the high-order
16 bits of the product into DM0101 and low-order 16 bits of the product into
DM0100.

➮ Refer to p. 3-150.
Application of DIV instruction
■ Total count average
Outputs the average of 3 counter values in 4-digit BCD.
(C001 + C002 + C003) ÷ 3
→ BCD output value
The BCD value is output to 7500 to 7515.
