The function and timing of the two interrupt pins (INT1 and INT2) are user-programmable through the I2C/SPI interface. The SDA

and SCL I2C connections are open drain and therefore require a pullup resistor as shown in the application diagram in Figure 3.

The INT1 and INT2 pins may also be configured for open-drain operation. If they are configured for open drain, external pullup

resistors are required.
