The 908E626 has six different interrupt sources as
The Low Voltage Interrupt (LVI) is related to the external
With LVI the H-bridges (high side MOSFET only) are
During STOP mode the LVI circuitry is disabled.
The High voltage Interrupt (HVI) is related to the external

System wake-up can be initiated by any of four events:
• A falling edge on the LIN pin
• A wake-up signal from the AWD
• An LVR condition
