Pin Function
Power-Good Output 2: Asserted when the following is true: (PWRGD1 = Asserted)
AND (Time after Assertion of PWRGD1 = Time PWRGD2, as programmed by the
capacitor on PGTIMER). Once PWRGD1 is asserted, the PGTIMER pin begins to
charge and PWRGD2 will assert when PGTIMER crosses the PWRGD2 threshold
