Most single-word instructions are executed in a single
instruction cycle, unless a conditional test is true or
the program counter is changed as a result of the
instruction. In these cases, the execution takes two
instruction cycles with the additional instruction
cycle(s) executed as a NOP. Notable exceptions are the
BRA (unconditional/computed branch), indirect CALL/
GOTO, all table reads and writes, and RETURN/RETFIE
instructions, which are single-word instructions but take
two or three cycles. Certain instructions that involve
skipping over the subsequent instruction require either
