I/O GPIO0[15] — General purpose digital input/output pin.
I/O SSP1_SSEL — Slave Select for SSP1.
- R — Function reserved.
O ENET_TXD1 — Ethernet transmit data 1 (RMII/MII interface).
I T0_CAP2 — Capture input 2 of timer 0.
- R — Function reserved.
- R — Function reserved.
I/O EMC_D11 — External memory data line 11.

- R — Function reserved.
O U0_TXD — Transmitter output for USART0. See Table 4
for
ISP mode.
I/O EMC_A13 — External memory address line 13.
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 GPIO5[0] — General purpose digital input/output pin.
- R — Function reserved.
I T3_CAP0 — Capture input 0 of timer 3.
O ENET_MDC — Ethernet MIIM clock.

- R — Function reserved.
I U0_RXD — Receiver input for USART0. See Table 4
for ISP
mode.
I/O EMC_A12 — External memory address line 12.
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).
I/O GPIO5[1] — General purpose digital input/output pin.
- R — Function reserved.
I T3_CAP1 — Capture input 1 of timer 3.
- R — Function reserved.
