Set Settings:Pin Configuration[MFP15_SEL0][MFP15_SEL1] = 00 to select VC7EN. When this mode is selected, the pin is used as an enable pin to control an NFET gate. The NFET enables/disables the external resistor divider, which translates the cell-7 positive terminal to a voltage between 0 V and 1.0 V to be digitized by the VC7SENSE pin. This pin is driven high to turn on the NFET and enable the divider. It is driven low to turn off the NFET and to disable the divider. The pulldown resistor to VSS ensures that the NFET gate turns off when the pin is driven high-Z (when the device is in SHUTDOWN).
