Skip the next half-words if the register's LSB is set (the value is odd).
A 2-bit field located in SRC2 contains the Skip Length, which is incremented to fit a value between 1 and 4 half-words, beginning after the skip instruction.
This instuction is also known under the alias SNE.
The Imm16 field is not used because the negation field already provides with a XOR.
This is one of the instructions of the SKIP group, see also : SKIP, SZ/SNZ, SNO/SE, SS/SNS.
