Command
input
FNC213
SFRP
1) 16 bits stored in a word device
Specify a value in the range from "0" to "15" as "n".
If "16" or larger value is specified as "n", 16 bits are shifted rightward by the remainder of "n/16".
For example, when "n" is set to "18", 16 bits are shifted rightward by 2 bits (18/16 = 1 ... 2).
2) The ON (1)/OFF (0) status of the "n"th bit (bit "n-1") in the word device
flag M8022.
3) "0" is set to "n" bits from the most significant bit.
