TMS320F280049C: Using all 4 SDFM inputs with Design Drive

Part Number: TMS320F280049C
Other Parts Discussed in Thread: TMDXIDDK379D,

The tmdxiddk379d with the TMS320F280049C doesn't use SDFM to measure current of each phase, only Vdc. Is it possible to use the 4 available SDFM channels to measure the current of 3 phases and DC bus voltage? It seems like the SD pins on the EVM board are beyond the 100pins of the control card, I'm assuming this is why.

If there are pins available and we use a self-built baseboard is this possible or is there a software reason why all 4 SDFM channels aren't usable along with BiSS and the 6x PWM outputs? 

Thanks

Chai
