Operands:
D: Device to be rotated n: Number of bits to be rotated in 1 rotation
Explanations:
1. If D is used in device F, only 16-bit instruction is applicable.
2. If D is designated as KnY, KnM, and KnS, only K4 (16-bit) and K8 (32-bit) are valid.
3. Range of n: K1 ~ K16 (16-bit); K1 ~ K32 (32-bit)
4. See the specifications of each model for their range of use.
5. Flag: M1022 (carry flag)
6. This instruction rotates the device content designated by D to the right for n bits.
7. This instruction adopts pulse execution instructions (RORP, DRORP).
Program Example:
When X0 = Off→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.
