- R — Function reserved.
I/O U0_UCLK — Serial clock input/output for USART0 in
synchronous mode.
I/O EMC_A11 — External memory address line 11.
O USB0_IND1 — USB0 port indicator LED control output 1.
I/O GPIO5[2] — General purpose digital input/output pin.
I CTIN_6 — SCTimer/PWM input 6. Capture input 1 of timer 3.
I T3_CAP2 — Capture input 2 of timer 3.
O EMC_CS1
— LOW active Chip Select 1 signal.

C1 data input/output (this pin does not use a
specialized I2C pad).
O U3_TXD — Transmitter output for USART3. See Table 4
for
ISP mode.
I 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.
O T3_MAT0 — Match output 0 of timer 3.
O 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.

I/O I2C1_SCL — I
2
C1 clock input/output (this pin does not use a
specialized I2C pad).
I U3_RXD — Receiver input for USART3. See Table 4
for ISP
mode.
I 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.
O T3_MAT1 — Match output 1 of timer 3.
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).
