Operands:

D: Device to be rotated n: Number of bits to be rotated in 1 rotation

Explanations:

1.This instruction rotates bit status of the device D together with M1022 to the left for n bits.

2.The status of the last bit rotated (marked with ※) is moved to the carry flag M1022.

3.This instruction is generally used in pulse execution mode (RCLP, DRCLP).

4.If operand D uses index F, only a 16-bit instruction is available.

5.If operand D is specified as KnY, KnM or KnS, only K4 (16-bit) or K8 (32-bit) is valid.

6.Valid range of operand n: 1≤ n ≤16 (16-bit), 1≤ n ≤32 (32-bit)

Program Example:

When X0 goes from OFF to ON, the 16 bits (4 bits as a group) in D10 together with carry flag M1022 (total 17 bits) will rotate to the left, as shown in the figure below. The bit marked with ※ will be sent to carry flag M1022.
