◆
Function
1) The bit pattern of a matrix composed of n 16-bit data entries in the range [S] to [S + n – 1] is shifted to
the left or right. If M8329 is set to ON, the shift direction is right; if it is set to OFF, the shift direction is
left. The bit position left blank after every shift, which is bit 0 in a left shift or bit (16n – 1) in a right shift,
is lled with the placeholder ag M8328. The bit moved out of the matrix, which is bit (16n – 1) in a left
shift or bit 0 in a right shift, is diverted to the carry ag M8327. The data after shift is stored in elements
from head address [D].
2) The instruction of the pulse execution type (MBSP) is generally used.

Application
Assume that M8329 = OFF. The bit pattern of the following matrix is shifted to the left:
0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1
0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1
