- R — Function reserved.
O MCOA1 — Motor control PWM channel 1, output A.
O 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.
- R — Function reserved.
I/O GPIO5[18] — General purpose digital input/output pin.
O ENET_TXD3 — Ethernet transmit data 3 (MII interface).
I/O SGPIO3 — General purpose digital input/output pin.
O U0_TXD — Transmitter output for USART0.

I/O GPIO4[11] — General purpose digital input/output pin.
O MCOB1 — Motor control PWM channel 1, output B.
I USB1_PWR_FAULT — USB1 Port power fault signal
indicating over-current condition; this signal monitors
over-current on the USB1 bus (external circuitry required to
detect over-current condition).
