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

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.
Example: If BITCNT = 3
