6.12.2 Explanation of Shift Instructions

Instruction code

Explanation:

The states of the n

these groups are shifted to the right. The states of the n

to the devices starting from D to fill the vacancy.

Generally, the pulse instruction SFTRP is used.

The operand n

should be within the range between 1 and 1024. The operand n

within the range between 1 and n

When X0.0 is switched 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 shifted to the right.

The shift of the states of the bit devices to the right during a scan is illustrated as follows.

Pulse instruction 16-bit instruction (9 steps) 32-bit instruction

S ： Initial device in which the value is shifted

D ： Initial device in which the value is shifted

： Length of the data which is shifted

： Number of bits forming a group

bit devices starting from D are divided into groups (n
