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 to the right for n bits

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

flag)

3. This instruction is generally used in pulse execution mode (RORP, DRORP).

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 will rotate to the right, as

shown in the figure below. The bit marked with ※ will be sent to carry flag M1022..
