Operands:
D: Device to be rotated n: Number of bits to be rotated in 1 rotation
Explanation:
1. This instruction rotates bit status of the device D together with M1022 to the right 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 (RCRP, DRCRP).
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 right, as shown in the figure below. The bit marked with ※
will be moved to carry flag M1022
