Run mode — This is the basic mode of operation. To conserve power in this mode, disable the
module.
Wait mode — The module continues to operate while the MCU is in wait mode and can provide
a wake-up interrupt.
Stop mode — 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.
