I/O P2[4] — General purpose digital input/output pin.
O
PWM1[5] — Pulse Width Modulator 1, channel 5 output.
I
DSR1 — Data Set Ready input for UART1.
O
TRACEDATA[1] — Trace data, bit 1.
P2[5]/PWM1[6]/
DTR1/
TRACEDATA[0]
68[1]
I/O P2[5] — General purpose digital input/output pin.
O
PWM1[6] — Pulse Width Modulator 1, channel 6 output.
O
DTR1 — Data Terminal Ready output for UART1. Can also be configured to be an
RS-485/EIA-485 output enable signal.
O
TRACEDATA[0] — Trace data, bit 0.
P2[6]/PCAP1[0]/
RI1/TRACECLK
67[1]
I/O P2[6] — General purpose digital input/output pin.
I
PCAP1[0] — Capture input for PWM1, channel 0.

O
RTS1 — Request to Send output for UART1. Can also be configured to be an
RS-485/EIA-485 output enable signal.
P2[8]/TD2/
TXD2
65[1]
I/O P2[8] — General purpose digital input/output pin.
O

P2[9]/
USB_CONNECT/
RXD2
64[1]
I/O P2[9] — General purpose digital input/output pin.
O
USB_CONNECT — Signal used to switch an external 1.5 kΩ resistor under
software control. Used with the SoftConnect USB feature. (LPC1769/68/66/65/64
only).
I
RXD2 — Receiver input for UART2.
P2[10]/EINT0/NMI 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.
I

I2STX_CLK
I
EINT1 — External interrupt 1 input.
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.
(LPC1769/68/67/66/65 only).
P2[12]/EINT2/
51[6]
I/O P2[12] — General purpose digital input/output pin.
I2STX_WS
I
EINT2 — External interrupt 2 input.
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.
(LPC1769/68/67/66/65 only).
