In Figure 14 and Table 24 the schematics and the recommended values for external

components are shown.

The decoupling capacitor for the supply should have a value of at least 10 nF.

In order to use the alert functionality, the ALERT/ADD1 pin must be connected via a pull up

resistor to VDD.

For the serial interface, pull up resistors to VDD are mandatory.

The pull up resistors on the serial interface and the interrupt depend on the bus capacitance

and on the clock speed.
