Communication buses

INT

Interrupt

A pin a chip pulls low/high to say "hey, I have new data ready."

How it looks

Real geometry: CORE3588 copper, drawn from our board file (top and bottom layers; this net in amber)

INT on CORE3588 (amber): net IMU_INT.

1The motion sensor U11 at this end...
2...to the computer module socket. This one wire is INT: "I have new data", from the sensor.

INT is one wire of an SPI bus; the others are SCK, MOSI, MISO, CS.
