* Summary:
* Wakeup on address match enabled: All incoming transaction will be NACKed till
* power down will be asserted. The address match event wakes up the chip.
* Wakeup on address match disabled: Disables active mode power template bits or
* clock gating as appropriate. Saves I2C configuration and non-retention
* register values.
* Disables I2C interrupt.
*
* Parameters:
* None
*
* Return:
* None
*
* Reentrant:
* No
