Instruction code

Explanation:

The values of the bits in the device specified by D are divided into groups (n bits as a group),

and these groups are rotated to the right with the carry flag SM602.

Only the 32-bit instructions can use the 32-bit counter.

The operand n used in the 16-bit instruction should be within the range between 1 and 16. The

operand n used in the 32-bit instruction should be within the range between 1 and 32.

Generally, the pulse instructions RCRP and DRCRP are used.

When X0.0 is switched from OFF to ON, the values of the bits in D10 are divided into groups (four

bits as a group), and these groups are rotated to the right with the carry flag SM602. (The value of

the bit marked ※ is transmitted to the carry flag SM602.)
