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.
