15.1 Introduction
15.2 Features
2010-09-06 - d0001_Rev1.00
The I
both a master and a slave, and supports multi-master buses. Both standard-mode, fast-mode and fast-
mode plus speeds are supported, allowing transmission rates all the way from 10 kbit/s up to 1 Mbit/s.
Slave arbitration and timeouts are also provided to allow implementation of an SMBus compliant system.
The interface provided to software by the I
process and close to automatic transfers. Automatic recognition of slave addresses is provided in all
energy modes.
• True multi-master capability
• Support for different bus speeds
• Arbitration for both master and slave (Allows SMBus ARP)
• Clock synchronization and clock stretching
• Hardware address recognition
• 10-bit address support
• Error handling
• Double buffered data
• Full DMA support
0 1 2 3
• Standard-mode (Sm) bitrate up to 100 kbit/s
• Fast-mode (Fm) bitrate up to 400 kbit/s
• Fast-mode Plus (Fm+) bitrate up to 1 Mbit/s
• 7-bit masked address
• General call address
• Active in all energy modes
• Clock low timeout
• Clock high timeout
• Arbitration lost
• Bus error detection

What?
The I
on I
consumption possible.
Why?
I
communication with a number of external
devices using only two I/O pins.
How?
With the help of DMA, the I
allows I
intervention. Address recognition is available
in all energy modes (except EM4), allowing
the MCU to wait for data on the I
sub-µA current consumption.
