Chapter 11 Inter-Integrated Circuit (S08IICV2)
11.1.1 Features
The IIC includes these distinctive features:
⢠Compatible with IIC bus standard
⢠Multi-master operation
⢠Software programmable for one of 64 different serial clock frequencies
⢠Software selectable acknowledge bit
⢠Interrupt driven byte-by-byte data transfer
⢠Arbitration lost interrupt with automatic mode switching from master to slave
⢠Calling address identiï¬cation interrupt
⢠Start and stop signal generation/detection
⢠Repeated start signal generation
⢠Acknowledge bit generation/detection
⢠Bus busy detection
⢠General call recognition
⢠10-bit address extension
11.1.2 Modes of Operation
A brief description of the IIC in the various MCU modes is given here.
⢠Run mode â This is the basic mode of operation. To conserve power in this mode, disable the
module.
⢠Wait mode â The module continues to operate while the MCU is in wait mode and can provide
a wake-up interrupt.
⢠Stop mode â The IIC is inactive in stop3 mode for reduced power consumption. The stop
instruction does not affect IIC register states. Stop2 resets the register contents.
