VR_EN 125 D04 H05 I Internal voltage regulator enable. Active-low
VR_PORT 62 L08 G02, L18
Internal voltage regulator input/output. When VR_EN is low, the
regulator is enabled and this terminal is an output. An external
bypass capacitor is required on this terminal. When VR_EN is high,
the regulator is disabled and this terminal is an input for an external
2.5-V core power source.
