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.

Note: Pullup resistors on INT1 and INT2 are not required if these
pins are configured for push/pull (default) operation.

Note: Pullup resistors on SCL/SCLK and SDA/MOSI are not
required if the device is operated in SPI Interface mode.
