TMS320F28377D: Sgma Delta Filter Module(SDFM)

Part Number: TMS320F28377D

Hi Champs,

I'd like to know the function of FEN bit of SDDFPARMx registers.

This bit enables or disables Filter module. The datasheet shows that Data Filter is disabled if this bit set to zero. If so, I like to know if a data value stored in data buffer is cleared to zero or stores the last value when FEN bit is changed from '1' to '0' during SDFM operation.   

Thanks,

Steve
