Shift Instructions
2
ArySHL and ArySHR
If InOut[] is BOOL data, the results will be the same as shifting a bit string of Size bits by Num bits.
• The shift operation is not performed if the value of Num is 0.
• If the value of Num is larger than Size, all values from InOut[0] to InOut[Size−1] are initialized.
• Return value Out is not used when the instruction is used in ST.
• An error occurs in the following case. ENO will be FALSE, and InOut[] will not change.
• The value of Size exceeds the array area of InOut[].
