Instruction code

Explanation:

The data in the n registers starting from D is shifted to the left, and the data in D is cleared to 0.

Generally, the pulse instruction NSFLP is used.

The operand n should be within the range between 1 and 512.

When X0.0 is ON, the data in D0~D5 is shifted to the left, and the data in D0 is cleared to 0.

Additional remark:

If D+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 512, the instruction is not executed, SM0 is ON, and the

error code in SR0 is 16#200B.
