PRODUCTION DATA
The SUSPEND state is a low-power mode of operation intended to support system standby. Typically all power rails are turned off with the exception of any rail with an SEQ register set to 0h. DCDC5 and DCDC6 also remain enabled if the freshness seal is broken. To enter the SUSPEND state, pull the PWR_EN pin low. All power rails controlled by the power-down sequencer are shut down, and after 500 ms the device enters the SUSPEND state. All rails not controlled by the power-down sequencer will maintain its state. Note: all register values are reset as the device enters the SUSPEND state. The device enters the ACTIVE state after it detects a wake-up event as described in the previous sections.
