I2C is a two-wire, bi-directional serial bus that
provides a simple and efficient method of
data transmission over a short distance be-
tween many devices. The DI2CS core pro-
vides an interface between a microprocessor
/microcontroller and an I2C bus. It can works
as a slave transmitter or slave receiver de-
pending on working mode determined by a
master device. The DI2CS core incorporates
all features required by the latest I2C specifi-
cation including clock synchronization, arbi-
tration and High-speed transmission mode.
The DI2CS supports all the transmission
speed modes.
