Instruction code

Explanation:

The values of the bits in D are shifted by n bits to the left. The vacancies (b0~bn-1) resulting

from the shift is filled by 0, and the value of b16-n is transmitted to SM602.

The operand n should be within the range between 1 and 16.

Generally, the pulse instruction SFLP is used.

When X0.0 is ON, the values of b0~b15 in D0 are shifted by 6 bits to the right, and the value of b10

is transmitted to SM602. The values of b0~b5 are cleared to 0 after the shift.

The shift of the values of the bits to the left during a scan is illustrated as follows.

→ Being carried (The value of b10 is transmitted to SM602.

Additional remark:

If n is less than 0, or if n is larger than 16, the instruction is not executed, SM0 is ON, and the error

code in SR0 is 16#200B.
