I C (inter-integrated circuit) bus Interface serves as an interface between the microcontroller
and the serial I
sequencing, protocol, arbitration and timing. It supports the standard mode (Sm, up to 100
kHz) and Fm mode (Fm, up to 400 kHz).
It may be used for a variety of purposes, including CRC generation and verification, SMBus
(system management bus) and PMBus (power management bus).
Depending on specific device implementation DMA capability can be available for reduced
CPU overload.
