LPC1311/13/42/43

32-bit ARM Cortex-M3 microcontroller

PIO0_3/USB_VBUS

14[1]

I/O

PIO0_3 — General purpose digital input/output pin. LPC1343 only: A LOW

level on this pin during reset starts the ISP command handler, a HIGH level

starts the USB device enumeration.

USB_VBUS — Monitors the presence of USB bus power (LPC1343 only).

PIO0_4/SCL

15[2]

I/O

PIO0_4 — General purpose digital input/output pin.

I/O

SCL — I2C-bus clock input/output. High-current sink only if I2C Fast-mode

Plus is selected in the I/O conﬁguration register.

PIO0_5/SDA

16[2]

I/O

PIO0_5 — General purpose digital input/output pin.

I/O

SDA — I2C-bus data input/output. High-current sink only if I2C Fast-mode

Plus is selected in the I/O conﬁguration register.

PIO0_6/USB_CONNECT/

SCK

22[1]

I/O

PIO0_6 — General purpose digital input/output pin.

USB_CONNECT — Signal used to switch an external 1.5 k

Ω resistor under

software control. Used with the SoftConnect USB feature (LPC1343 only).

I/O

SCK — Serial clock for SSP.

PIO0_7/CTS

23[1]

I/O
