The CS35L45 features a low-power Hibernation State. In this state, all register contents are lost, but the contents of RAM are retained. In the Hibernation State, only always-on digital functions to support wake-up are enabled. Entry to this state is achieved via the register interface (either by an external driver using the control port, or the programmable DSP). Exit from this state is triggered by activity on device GPIO pins, intended SPI transaction, or I2C transaction with intended slave address
