Impulse noise sources such as EMI, crosstalk, and so on, has the possibility of corrupting SDCLK and SDDATA bit streams, resulting in corrupted SDFM filtered data. This impulse noise effects can be mitigated when using the input qualification feature that synchronizes SDCLK/SDDATA signals with PLLCLK. By default, both SDCLK and SDDATA bit stream are not synchronized. SDCLK can be synchronized to PLLCLK by setting SDCTLPARMx.SDCLKSYNC = 1 and SDDATA can be synchronized to PLLCLK by setting SDCTLPARMx.SDDATASYNC = 1. Figure 7-317 shows optional Input Qualification option on SDCLK and SDDATA lines.
