SCQ

Unconditionally skip the next half-words.

The Skip Length is not given by the 2-bit field located in SRC2 but by the 2-bit CQ register. The value is incremented to fit a value between 0 and 3 half-words after the SCQ instruction (so the skip won't go to itself).

Because it is unconditional, the SRC1 field is ignored, as well as the optional immediate field, so it is normally used as a short instruction.
