Operands:
S : Matrix source device D : Operation result n : Array length
Explanations:
1. Range of n : K1 ~ K256
2. S designates KnX, KnY, KnM and KnS; D designates KnY, KnM and KnS.
3. SA/SX/SC can designate n = 4. EH/EH2/SV can designate n 4
≦
.
4. See the specifications of each model for their range of use.
5. Flags: M1095, M1097. See remarks for more details.
6. This instruction performs left-right rotation on the matrix bits in S according to array length n . M1097
determines the left (M1097 = 0) or right (M1097 = 1) rotation of matrix bits. The empty bits derived from every
rotation of 1 bit (when left rotation: b
0
; when right rotation: b
16n-1
) is filled by rotation bits (when left rotation:
b
16n-1
; when right rotation: b
0
). The result is stored in D . Rotation bits not only fill the empty bits but also send
the status of bits to the carry flag M1095.
7. The pulse execution instruction MBRP is generally adopted.
Program Example 1:
When X0 = On, M1097 = Off, indicating a left matrix rotation is performed. The 16-bit registers D0 ~ D2 will perform a
left matrix rotation and the result will be stored in the matrix of the 16-bit registers D20 ~ D22. The carry flag M1095
will be “1”.
