PIN FUNCTIONS
UV0, UV1 (Pin 33, Pin 34): Undervoltage Three-Level
Inputs. These pins may be tied to VREG, VREF or V. UV1
and UV0 select the undervoltage threshold and each pin
has an internal pull-up to VREG. See Table 2.
OV0, OV1 (Pin 35, Pin 36): Overvoltage Three-Level
Inputs. These pins may be tied to VREG, VREF or V. OV1
and OV0 select the overvoltage threshold and each pin
has an internal pull-down to V. See Table 1.
