Bits 15:12 – HCFSEL[3:0] Hysteretic Comparator Function Input Select bits

The selected input signal controls the switching between the DACx high limit (DACxDATH) and the DACx low limit (DACxDATL) as the data source for the PDM DAC. It modifies the polarity of the comparator, and the rising and falling edges initiate the start of the LEB counter (TMCB[9:0] bits in DACxCONH).
