The VDIV pin provides an option to make ACREFN a small positive voltage if required. The VDIV pin is driven when the analog comparators are in use, and this signal can be used along with a voltage divider arrangement to create a small positive offset on the ACREFN pin. The VDIVEN option can be used optionally with any of the QMatrix modes discussed in the previous sections. Typical values for Ra and Rb are Ra=16500 ohm and Rb = 50 ohm. Assuming a 3.3V I/O supply, this will shift the comparator threshold by 3.3V*(Rb/(Ra+Rb)) which is 10 mV. The VDIVEN pin option usage in the Internal Discharge mode scenario is shown in case E.
