VMSET/MODE -
This pin is a dual function pin. Tie this pin to
VCC5 to disable voltage margining. When not tied to VCC5,
this pin serves as VMSET. Connect a resistor from this pin to
ground to set the delta for voltage margining. If voltage
margining and external reference tracking mode are not
needed, this pin can be tied directly to ground.
GPIO2
- This is general purpose IO pin for voltage
margining. Refer to Table 2.

NOTES:
1. The GPIO1/REFIN and GPIO2 pins cannot be left floating.
2. Ensure that GPIO1/REFIN is tied high prior to the logic change at VMSET/MODE.
