12 Appendix B: Instruction Set Overview
12.4 Multi-Word Instructions
The instructions in Table 24 - SX Multi-Word Instructions are translated into two or more single word
instructions by the assembler.
Important: All single-word skip instructions (see Table 23 - SX Single-Word Instructions) advance the
program counter by one only. Therefore, make sure that a skip is never immediately followed by a multi-word
instruction, because this will most likely generate a lot of trouble. Also note that most of the multi-word
instructions make use of W as a temporary register, without preserving its original value.
