Place data so the top 16 bits of the modulo start and end address are the same, since the modulo
start address only swaps the bottom 16 bits of the address register.
Note: When using addition index as the DSP data addressing, the address pointer may exceed
4.5.4
The following shows how DSP addressing works in the execution stage (EX) of a pipeline
(including modulo addressing).

the modulo start address.
