Skip the next half-words if the register's LSB is set (the value is odd).
The 4-bit SRC2 field contains the Skip Length, a signed integer (between -8 and 7) that indicates how many half-words must be skipped (from the instruction's opcode address).
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.
