Instruction code

Explanation:

The instruction is used to count the bits with the value 1 or 0 in the n devices starting from the

device specified by S. The operation result is stored in D.

When SM617 is ON, the bits with the value 1 is counted. When SM617 is OFF, the bits with the

value 0 is counted. When the operation result is 0, SM618 is ON.

The operand n should be within the range between 1 and 256.

Suppose SM617 is ON. When X0.0 is ON, the bits with the value 1 are counted, and the operation

result is stored in D20. Suppose SM617 is OFF. When X0.0 is ON, the bits with the value 0 are

counted, and the operation result is stored in D20.

Additional remark:

If S+n-1 exceeds the device range, the instruction is not executed, SM0 is ON, and the error

code in SR0 is 16#2003.

If n is less than 1, or if n is larger than 256, the instruction is not executed, SM0 is ON, and the

error code in SR0 is 16#200B.

SM617: The bits with the value 0 or 1 are counted.

SM618: It is ON when the matrix counting result is 0.
