U3_RXD — Receiver input for USART3.
R — Function reserved.
MCOA1 — Motor control PWM channel 1, output A.
USB1_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.
