3.3.19.2.3 Instruction Stalls and REPEAT Loops

Other than the addition of instruction stall cycles, RAW data dependencies do not affect the operation of either DO or REPEAT loops.

The prefetched instruction within a REPEAT loop does not change until the loop is complete or an exception occurs. Although register dependency checks occur across instruction boundaries, the dsPIC33A devices effectively compare the source and destination of the same instruction during a REPEAT loop.
