Arduino Timer Interrupts - HobbyTronics
The processor at the heart of any Arduino has two different kinds of interrupts: “external”, and “pin change”. There are only two external interrupt pins on the ATmega168 /328 (ie, in the Arduino Uno/Nano/Duemilanove), INT0 and INT1 , and they are mapped to Arduino pins 2 and 3.

/9/2015I do use the Arduino interrupt. The MCP23017 generates an interrupt on a pin change of any of the 16 ports. That interrupt is then detected by the Arduino. That interrupt tells it to enquire (via I2C) about the status of the pins.

How to interrupt on a data ready trigger when communications to the sensor are interrupt driven? (as @hauptmech mentioned): re-enable I2C interrupt inside of ISR. Isn't this approach discouraged? Use non-interrupt-driven I2C (polling)--supposedly a dangerous approach inside of ISRs. , you could write one interrupt handler that handles a
Interrupt based I2C communication - Question - Mbed
Once you've installed the library you can connect the sensor board via I2C or SPI to your Arduino, it will work with any kind or flavor. If you're using a different kind of microcontroller, the library is a good reference to help you port the code over. Using the external IRQ Interrupt Arduino has some basic ability to attach to pin
