4.10 Inter-Integrated Circuit (I2C)

The 280x device contains one I2C Serial Port.

Figure 4-15

shows how the I2C peripheral module

interfaces within the 280x device.

The I2C module has the following features:

•

Compliance with the Philips Semiconductors I2C-bus specification (version 2.1):
–

Support for 1-bit to 8-bit format transfers

–

7-bit and 10-bit addressing modes

–

General call

–

START byte mode

–

Support for multiple master-transmitters and slave-receivers

–

Support for multiple slave-transmitters and master-receivers

–

Combined master transmit/receive and receive/transmit mode

–

Data transfer rate of from 10 kbps up to 400 kbps (I2C Fast-mode rate)

•

One 16-word receive FIFO and one 16-word transmit FIFO

•

One interrupt that can be used by the CPU. This interrupt can be generated as a result of one of the
following conditions:
–

Transmit-data ready

–

Receive-data ready

–

No-acknowledgment received

–

Arbitration lost

–

Stop condition detected

–

Addressed as slave

•

An additional interrupt that can be used by the CPU when in FIFO mode

•

Module enable/disable capability

•

Free data format mode
