C28 Inter-Integrated Circuit Module - Texas Instruments Concerto F28M36 Series Technical Reference Manual

Table of Contents

This chapter describes the features and operation of the inter-integrated circuit (I2C) module. The I2C

module provides an interface between one of these devices and devices compliant with Philips

Semiconductors Inter-IC bus (I2C-bus) specification version 2.1 and connected by way of an I2C-bus.

External components attached to this 2-wire serial bus can transmit/receive 1 to 8-bit data to/from the

device through the I2C module. This guide assumes the reader is familiar with the I2C-bus specification.

NOTE: A unit of data transmitted or received by the I2C module can have fewer than 8 bits;

however, for convenience, a unit of data is called a data byte throughout this document. The

number of bits in a data byte is selectable via the BC bits of the mode register.
