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 the VBUS
signal 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.
I/O SGPIO4 — General purpose digital input/output pin.
O EMC_CS1
— LOW active Chip Select 1 signal.
- R — Function reserved.
I T2_CAP2 — Capture input 2 of timer 2.
- R — Function reserved.
- R — Function reserved.

I/O GPIO0[5] — General purpose digital input/output pin.
O EMC_BLS1
— LOW active Byte Lane select signal 1.
I/O SGPIO5 — General purpose digital input/output pin.
I USB0_PWR_FAULT — Port power fault signal indicating
overcurrent condition; this signal monitors over-current on the
USB bus (external circuitry required to detect over-current
condition).
- R — Function reserved.
I T2_CAP3 — Capture input 3 of timer 2.
