TMS570LS0714 Pin Multiplexing

Other Parts Discussed in Thread: TMS570LS1224

Hello team,

When looking at the technical reference manuals for the TMS570LS0714 and the TMS570LS1224, I noticed that some modules were duplicated in the table for pin multiplexing (table 4-20 in theTMS570LS0714 technical reference manual). For example, for the TMS570LS0714, EPWM1SYNCO can be muxed through pins E3 or A4. In the cases of these duplicates, can both pins be outputs for the same signal? If both are used, do they have the same exact output?

Thanks!

Yes, and they would both output the same signal. The purpose of the duplication is really to support having this signal available on the smaller 144 pin package.

That makes sense for all cases except for EMIF_DATA_11 on the TMS570LS1224. The same pin (PINMMR6) can be muxed to EMIF_DATA_11 using either bit 8 or 9. Was that intentional?

Hey Bob - looping back here. Can you address the above?

Thanks,

Alex
