I/O SGPIO6 — General purpose digital input/output pin.

I/O U0_UCLK — Serial clock input/output for USART0 in

synchronous mode.

I/O EMC_A11 — External memory address line 11.

USB0_IND1 — USB0 port indicator LED control output 1.

I/O GPIO5[2] — General purpose digital input/output pin.

CTIN_6 — SCTimer/PWM input 6. Capture input 1 of timer 3.

T3_CAP2 — Capture input 2 of timer 3.

R — Function reserved.

P2_3

J12

G11

[3]

I/O SGPIO12 — General purpose digital input/output pin.

I/O I2C1_SDA — I2C1 data input/output (this pin does not use a

specialized I2C pad).

U3_TXD — Transmitter output for USART3.

CTIN_1 — SCTimer/PWM input 1. Capture input 1 of timer 0.

Capture input 1 of timer 2.

I/O GPIO5[3] — General purpose digital input/output pin.

R — Function reserved.

T3_MAT0 — Match output 0 of timer 3.

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.

P2_4

K11

[3]

I/O SGPIO13 — General purpose digital input/output pin.

I/O I2C1_SCL — I2C1 clock input/output (this pin does not use a

specialized I2C pad).

U3_RXD — Receiver input for USART3.

CTIN_0 — SCTimer/PWM input 0. Capture input 0 of timer 0,

1, 2, 3.

I/O GPIO5[4] — General purpose digital input/output pin.

R — Function reserved.

T3_MAT1 — Match output 1 of timer 3.

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).
