In systems, the modulator clock can be generated using PWMs. Assuming all the SD-CLKs see the same delay on board traces, you can potentially use just one clock to clock multiple filters; thereby, saving on the number of pins used for SDFM. To enable this, Filter1 SDCLK (SD-C1) can possibly apply to other filter channels if required. The SDCTLPARAMx.SDCLKSEL register bit field can be configured to select filter channel SDCLK. See Figure 32-6 to view this feature.
