VSEL pin strap is used to program initial boot voltage value from 0.6 V to 1.1 V by the resistor connected from VSEL to AGND. The initial boot voltage is used to program the main loop voltage reference point. VSEL voltage settings provide TI designated discrete internal reference voltages. Table 2 lists internal reference voltage selections.
