ADAU1702 hysteresis settings

I don't understand the auxiliary ADC hysteresis settings:



  • 00  4-bit hysteresis (12-bit level)
  • 01  5-bit hysteresis (12-bit level)
  • 10  Filter and hysteresis bypassed
  • 11  Low-pass filter bypassed


So with FIL=11, which hysteresis is used?


In SigmaStudio it just says "No hysteresis", with no mention of filter being bypassed:

  • 00 4-bit Hysteresis
  • 01 5-bit Hysteresis
  • 10 No Hysteresis
  • 11 No Low Pass Filter


So there's no setting to disable hysteresis and keep the lowpass filter?  I have to add my own in software?
