 Note: The instruction supports V devices and Z devices. (If the 16-bit
instruction is used, Z devices can not be used. If the 32-bit instruction
is used, V devices can not be used.)

Explanation
 S: Initial bit device which is moved; D: Initial bit device which is moved; n
1
:
Number of bits which are moved; n
2
: Number of bits forming a group
 The states of the n
1
bit devices starting from D are divided into groups (n
2
bits as
a group), and these groups are moved leftwards. The states of the n
2
bit devices
starting from S are moved to the vacant devices in the devices starting from D.
 Generally, the pulse instruction SFTRP is used.

Example
 When X0 is turned from OFF to ON, the states of the sixteen bit devices starting
from M0 are divided into groups (four bits as a group), and these groups are
moved leftwards.
 The states of the bit devices are moved leftwards in the order ~ during a
scan cycle.
