Output (O): INT, DINT
1.28 µs
Input bits (I) are rotated to the right by the number (N) of bits defined by BITCNT. The N
least significant bits (LSB) of the input are stored as the N most significant bits (MSB) of
the output.
Example: If BITCNT = 3
I 1 1 1 0 0 0 0 0 1 1 1 0 0 1 0 1 1 1 0 1 0 0 1 1 0 0 1 1 0 1 0 1

Input bits (I) are rotated to the left by the number (N) of bits defined by BITCNT. The N
most significant bits (MSB) of the input are lost and the N least significant bits (LSB) of
the output are set to 0.
