- ^[2] N; PU I/O GPIO4[14] — General purpose digital input/output pin.
O MCOB2 — Motor control PWM channel 2, output B.
- R — Function reserved.
- R — Function reserved.
I/O I2S0_TX_SDA — I²S transmit data. It is driven by the
transmitter and read by the receiver. Corresponds to the signal
SD in the I²S-bus specification.
I ENET_RXD3 — Ethernet receive data 3 (MII interface).
- R — Function reserved.
I/O SSP0_MOSI — Master Out Slave in for SSP0.
- ^[2] N; PU I/O GPIO4[15] — General purpose digital input/output pin.
O MCOA0 — Motor control PWM channel 0, output A.
O USB1_IND1 — USB1 Port indicator LED control output 1.
- R — Function reserved.
- R — Function reserved.
I ENET_RXD2 — Ethernet receive data 2 (MII interface).
- R — Function reserved.
O U3_TXD — Transmitter output for USART3.
- ^[2] N; PU - R — Function reserved.
O MCOB0 — Motor control PWM channel 0, output B.
O USB1_IND0 — USB1 Port indicator LED control output 0.
- R — Function reserved.
I/O GPIO5[17] — General purpose digital input/output pin.
O ENET_TXD2 — Ethernet transmit data 2 (MII interface).
- R — Function reserved.
I U3_RXD — Receiver input for USART3.
69 ^[2] N; PU - R — Function reserved.
O MCOA1 — Motor control PWM channel 1, output A.
O USB1_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.
I/O GPIO5[18] — General purpose digital input/output pin.
O ENET_TXD3 — Ethernet transmit data 3 (MII interface).
- R — Function reserved.
O U0_TXD — Transmitter output for USART0.
