Inter-Integrated Circuit Interface (I
2
C)
The I
2
C module provides an interface between the MCU and a serial I
2
C-bus. It is capable of
acting as 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
2
C
module, allows both fine-grained control of the transmission process and close to automatic
transfers. Automatic recognition of slave addresses is provided in all energy modes.
