I/O GPIO3[2] — General purpose digital input/output pin.

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.

EMC_CS1 — LOW active Chip Select 1 signal.

R — Function reserved.

T2_CAP2 — Capture input 2 of timer 2.

R — Function reserved.

I/O GPIO3[3] — General purpose digital input/output pin.

CTIN_6 — SCT input 6. Capture input 1 of timer 3.

U0_TXD — Transmitter output for USART0.

EMC_CAS — LOW active SDRAM Column Address Strobe.

R — Function reserved.

I/O GPIO3[4] — General purpose digital input/output pin.

CTOUT_6 — SCT output 6. Match output 2 of timer 1.

U0_RXD — Receiver input for USART0.

EMC_RAS — LOW active SDRAM Row Address Strobe.

R — Function reserved.

I/O GPIO0[5] — General purpose digital input/output pin.

EMC_BLS1 — LOW active Byte Lane select signal 1.

I/O SGPIO5 — General purpose digital input/output pin.

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.

T2_CAP3 — Capture input 3 of timer 2.

R — Function reserved.
