5
Shifting n-bit(s) data to the right by (n) bit(s)
SFTR(P)
These instructions shift (n1) bits of data to the right by (n2) bit(s) from the device specified by (d).
Setting data

Descriptions, ranges, and data types
*1 Set so that n2

n1.
■
Applicable devices
*1 T, ST, C cannot be used.
*2 Only 0 or 1 can be used.
Processing details
• These instructions shift (n1) bits of data to the right by (n2) bit(s) from the device specified by (d). After the shift, (n2) points
from (s) are set into (n2) points from (d)+(n1-n2).
• When K0 is specified for (s), set 0s for (n2) points of bits from (d)+(n1-n2) after the shift.
• When K1 is specified for (s), set 1s for (n2) points of bits from (d)+(n1-n2) after the shift.

Error code
(SD0/SD8067) Remarks
2820 The (n2) points of data starting from the device specified by (s) exceed in the corresponding device.
The (n1) points of data starting from the device specified by (d) exceed in the corresponding device.
2821 The transfer source data (s) overlaps with shift device (d).
3405 A constant other than K0 or K1 is specified when the constant (s) is specified.
The values specified in (n1) and (n2) are such that (n1)<(n2).
