Run mode — This is the basic mode of operation. To conserve power in this mode, disable the
module.
Wait mode — The module will continue 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 will reset the register contents.
