LPC2364/66/68

Fast communication chip

P2[10]/EINT0

53[6]

I/O

P2[10] — General purpose digital input/output pin.

Note: LOW on this pin while RESET is LOW forces on-chip bootloader to take over

control of the part after a reset.

EINT0 — External interrupt 0 input.

P2[11]/EINT1/

MCIDAT1/

I2STX_CLK

52[6]

I/O

P2[11] — General purpose digital input/output pin.

EINT1 — External interrupt 1 input.

MCIDAT1 — Data line for SD/MMC interface. (LPC2368 only)

I/O

I2STX_CLK — Transmit Clock. It is driven by the master and received by the slave.

Corresponds to the signal SCK in the

I2S-bus speciﬁcation.

P2[12]/EINT2/

MCIDAT2/

I2STX_WS

51[6]

I/O

P2[12] — General purpose digital input/output pin.

EINT2 — External interrupt 2 input.

MCIDAT2 — Data line for SD/MMC interface. (LPC2368 only)

I/O

I2STX_WS — Transmit Word Select. It is driven by the master and received by the

slave. Corresponds to the signal WS in the

I2S-bus speciﬁcation.

P2[13]/EINT3/

MCIDAT3/

I2STX_SDA

50[6]

I/O

P2[13] — General purpose digital input/output pin.

EINT3 — External interrupt 3 input.

MCIDAT3 — Data line for SD/MMC interface. (LPC2368 only)

I/O

I2STX_SDA — Transmit data. It is driven by the transmitter and read by the receiver.

Corresponds to the signal SD in the

I2S-bus speciﬁcation.

P3[0] to P3[31]

I/O

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 0 through 24, and 27 through 31 of this port are not available.

P3[25]/MAT0[0]/

PWM1[2]

27[1]

I/O

P3[25] — General purpose digital input/output pin.

MAT0[0] — Match output for Timer 0, channel 0.

PWM1[2] — Pulse Width Modulator 1, output 2.

P3[26]/MAT0[1]/

PWM1[3]

26[1]

I/O

P3[26] — General purpose digital input/output pin.

MAT0[1] — Match output for Timer 0, channel 1.

PWM1[3] — Pulse Width Modulator 1, output 3.

P4[0] to P4[31]

I/O

Port 4: Port 4 is a 32-bit I/O port with individual direction controls for each bit. The

operation of port 4 pins depends upon the pin function selected via the Pin Connect

block. Pins 0 through 27, 30, and 31 of this port are not available.

P4[28]/MAT2[0]/

TXD3

82[1]

I/O

P4[28] — General purpose digital input/output pin.

MAT2[0] — Match output for Timer 2, channel 0.

TXD3 — Transmitter output for UART3.

P4[29]/MAT2[1]/

RXD3

85[1]

I/O

P4[29] — General purpose digital input/output pin.

MAT2[1] — Match output for Timer 2, channel 1.

RXD3 — Receiver input for UART3.

TDO

1[1]

TDO — Test Data out for JTAG interface.

TDI

2[1]

TDI — Test Data in for JTAG interface.

TMS

3[1]

TMS — Test Mode Select for JTAG interface.

TRST

4[1]

TRST — Test Reset for JTAG interface.

TCK

5[1]

TCK — Test Clock for JTAG interface.
