I2C-bus interface

The I2C-bus interface is available on all parts.

Read this chapter if you want to understand the I2C operation and the software interface and want to learn how to use the I2C for wake-up from reduced power modes.

The LPC81x provides an on-chip ROM-based I2C API to configure and operate the I2C. See I2C API I2C API calls.

See CODE I2C Definitions for code examples that explain how to program the register interface.
