GPIO LINES

The ICM-30630 supports three bidirectional GPIO lines that can be configured as general purpose I/O, interrupt input, or
interrupt output. All GPIO voltage levels are referenced to VDDIO.

We recommend the following GPIO usage assignment:

Use ICM-30630 GPIO0 as output to wakeup host MCU. Connect the GPIO0 to host MCU wake-up interrupt
input.

Use ICM-30630 GPIO1 as output for general (non-wakeup) interrupt of host MCU. Connect the GPIO1 to host
MCU interrupt input.

ICM-30630 GPIO2 is used as a sensor interrupt input or GPIO.

Host wakes up ICM-30630 with an interrupt write via digital serial interface.
