I/O GPIO3[2] — General purpose digital input/output pin.
O USB0_PPWR — VBUS drive signal (towards external charge
pump or power management unit); indicates that VBUS must
be driven (active HIGH). Add a pull-down resistor to disable the
power switch at reset. This signal has opposite polarity
compared to the USB_PPWR
used on other NXP LPC parts.
