Operands:
S: Matrix source device n: Array length D: Counting result
Explanations:
1. Range of n: K1 ~ K256
2. S designates KnX, KnY, KnM and KnS; D designates KnY, KnM and KnS.
3. SA/SX/SC can designate n = 4. EH/EH2/SV can designate n 4≦ .
4. See the specifications of each model for their range of use.
5. Flags: M1098, M1099. See remarks for more details.
6. This instruction counts the number of bits which are “1” or “0” in S by array length n. The result is stored in D.
7. The instruction counts the number of bits which are “1” when M1098 = 1 and counts the number of bits which
are “0” when M1098 = 0. When the operation result is “0”, M1099 = 1.
Program Example:
When X10 = On, in the matrix of D0 ~ D2, when M1098 = 1, the instruction counts the total number of bits which are
“1” and store the number in D10. When M1098 = 0, the instruction counts the total number of bits which are “0” and
store the number in D10.
