Processing details
• This instruction shifts (n1) words of data to the right by (n2) word(s) from the device specified by (d). After the shift, (n2)
points from (s) are set into (n2) points from (d)+(n1-n2).
• This instruction sets the specified value for (n2) points of devices from (d) + (n1-n2) after the shift when K is specified for
(s).
