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):
â Support for 1-bit to 8-bit format transfers
â 7-bit and 10-bit addressing modes
â General call
â START byte mode
â Support for multiple master-transmitters and slave-receivers
â Support for multiple slave-transmitters and master-receivers
â Combined master transmit/receive and receive/transmit mode
â Data transfer rate of from 10 kbps up to 400 kbps (Philips Fast-mode rate)
⢠One 16-bit receive FIFO and one 16-bit 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:
â Transmit-data ready
â Receive-data ready
â Register-access ready
â No-acknowledgment received
â Arbitration lost
â Stop condition detected
â 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
