Description
P2[7] — General purpose digital input/output pin.
RD2 — CAN2 receiver input. (LPC2378 only)
RTS1 — Request to Send output for UART1.
TRACEPKT2 — Trace Packet, bit 2.
P2[8] — General purpose digital input/output pin.
TD2 — CAN2 transmitter output. (LPC2378 only)
TXD2 — Transmitter output for UART2.
TRACEPKT3 — Trace Packet, bit 3.
P2[9] — General purpose digital input/output pin.
USB_CONNECT1 — USB1 Soft Connect control. Signal used to switch an external
1.5 k resistor under the software control. Used with the SoftConnect USB feature.
(LPC2378 only)
RXD2 — Receiver input for UART2.
EXTIN0 — External Trigger Input.
P2[10] — General purpose digital input/output pin.
Note: LOW on this pin while RESET is LOW forces on-chip boot-loader to take over
control of the part after a reset.
EINT0 — External interrupt 0 input.
P2[11] — General purpose digital input/output pin.
EINT1 — External interrupt 1 input.
MCIDAT1 — Data line for SD/MMC interface.
I2STX_CLK — Transmit Clock. It is driven by the master and received by the slave.
Corresponds to the signal SCK in the I
P2[12] — General purpose digital input/output pin.
EINT2 — External interrupt 2 input.
MCIDAT2 — Data line for SD/MMC interface.
I2STX_WS — Transmit Word Select. It is driven by the master and received by the
slave. Corresponds to the signal WS in the I
P2[13] — General purpose digital input/output pin.
EINT3 — External interrupt 3 input.
MCIDAT3 — Data line for SD/MMC interface.
I2STX_SDA — Transmit data. It is driven by the transmitter and read by the receiver.
Corresponds to the signal SD in the I
Port 3: Port 3 is a 32 bit I/O port with individual direction controls for each bit. The
operation of port 3 pins depends upon the pin function selected via the pin connect
block. Pins 8 through 22, and 27 through 31 of this port are not available.
P3[0] — General purpose digital input/output pin.
D0 — External memory data line 0.
P3[1] — General purpose digital input/output pin.
D1 — External memory data line 1.
P3[2] — General purpose digital input/output pin.
D2 — External memory data line 2.
