6.9.7 Inter-Integrated Circuit
6.9.7.1 I²C Device-Specific Information
The device contains one I²C serial port. Figure 6-36 shows how the I²C peripheral module interfaces
within the 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 4-word receive FIFO and one 4-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
– Register-access 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
