I got a ICM-42670P, where VDD is connected to a back-up (denoted VDD_BACKUP) supply(3.3V), and VDDIO is connected to a seperate voltage source (denoted VDD3_3V) (3.3V).
I am configuring the IMU to WOM with both voltage sources high, and then i turn off VDD3_3V, because it turns of my MCU. And I was hoping to generate an interrupt (WOM) and use that to re-enable my VDD3_3V. But I am unable to detech any interrupts with VDDIO off? Is that expected?

Hi,
Yes, you need to route power to pin 5 VDDIO.
