logic

state

input

[1]

RESET/PIO0_0

3[2] yes I

I; PU

RESET — External reset input with 20 ns glitch filter. A LOW-going

pulse as short as 50 ns on this pin resets the device, causing I/O

ports and peripherals to take on their default states, and processor

execution to begin at address 0.

I/O -

PIO0_0 — General purpose digital input/output pin with 10 ns glitch

filter.

PIO0_1/CLKOUT/

CT32B0_MAT2/

USB_FTOGGLE

4[3] yes

I/O I; PU PIO0_1 — General purpose digital input/output pin. A LOW level on

this pin during reset starts the ISP command handler or the USB

device enumeration (USB on LPC1342/43 only, see description of

PIO0_3).

O-

CLKOUT — Clockout pin.

O-

CT32B0_MAT2 — Match output 2 for 32-bit timer 0.

O-

USB_FTOGGLE — USB 1 ms Start-of-Frame signal (LPC1342/43

only).

PIO0_2/SSEL0/

CT16B0_CAP0

10[3] yes

I/O I; PU PIO0_2 — General purpose digital input/output pin.

I/O -

SSEL0 — Slave select for SSP0.

I

-

CT16B0_CAP0 — Capture input 0 for 16-bit timer 0.

PIO0_3/USB_VBUS

14[3] yes

I/O I; PU PIO0_3 — General purpose digital input/output pin. LPC1342/43

only: A LOW level on this pin during reset starts the ISP command

handler, a HIGH level starts the USB device enumeration.

I

-

USB_VBUS — Monitors the presence of USB bus power

(LPC1342/43 only).

PIO0_4/SCL

15[4] yes I/O I; IA PIO0_4 — General purpose digital input/output pin (open-drain).

I/O -

SCL — I2C-bus clock input/output (open-drain). High-current sink

only if I2C Fast-mode Plus is selected in the I/O configuration

register.

PIO0_5/SDA

16[4] yes I/O I; IA PIO0_5 — General purpose digital input/output pin (open-drain).

I/O -

SDA — I2C-bus data input/output (open-drain). High-current sink

only if I2C Fast-mode Plus is selected in the I/O configuration

register.

PIO0_6/

USB_CONNECT/

SCK0

22[3] yes

I/O I; PU PIO0_6 — 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 (LPC1342/43 only).

I/O -

SCK0 — Serial clock for SSP0.

PIO0_7/CTS

23[3] yes

I/O I; PU PIO0_7 — General purpose digital input/output pin (high-current

output driver).

I

-

CTS — Clear To Send input for UART.

PIO0_8/MISO0/

CT16B0_MAT0

27[3] yes

I/O I; PU PIO0_8 — General purpose digital input/output pin.

I/O -

MISO0 — Master In Slave Out for SSP0.

O-

CT16B0_MAT0 — Match output 0 for 16-bit timer 0.
