Description
R — Function reserved.
ENET_TXD1 — Ethernet transmit data 1 (RMII/MII interface).
T0_CAP2 — Capture input 2 of timer 0.
R — Function reserved.
R — Function reserved.
R — Function reserved.
U0_TXD — Transmitter output for USART0.
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.
R — Function reserved.
T3_CAP0 — Capture input 0 of timer 3.
ENET_MDC — Ethernet MIIM clock.
R — Function reserved.
U0_RXD — Receiver input for USART0.
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.
T3_CAP1 — Capture input 1 of timer 3.
R — Function reserved.
