• Range slave address support
• DMA support
• Run mode: This is the basic mode of operation. To conserve power in this mode,
• Wait mode: The module continues to operate when the core is in wait mode and can
• Stop mode: The module is inactive in stop mode for reduced power consumption,
disable the module.
provide a wakeup interrupt.
except that address matching is enabled in stop mode. The STOP instruction does not
affect the I2C module's register states. In any VLLSx mode, the register contents are
reset.
