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
