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 displacement on the matrix bits in S according to array length n. M1097
determines the left (M1097 = 0) or right (M1097 = 1) displacement of matrix bits. The empty bits derived from
every displacement of 1 bit (when left displacement: b
0
; when right displacement: b
16n-1
) is filled by the status of
the complement flag (M1096). The spare bits (when left displacement: b
16n-1
; when right displacement: b
0
) are
sent to the carry flag (M1095). The result is stored in D.
7.
The pulse execution instruction MBSP is generally adopted.
Program Example 1:
When X0 = On, M1097 = Off, indicating a left matrix displacement is performed. Set M1096 = 0 and the 16-bit
registers D0 ~ D2 will perform a left matrix displacement and the result will be stored in the matrix of the 16-bit
registers D20 ~ D22. The carry flag M1095 will be “1”.
