All possible settings and result data can be accessed via the standard I[2] C interface. A typical application circuit is shown in Fig. 6 below. The additional 0.1 μF capacitor near the VDD pin in the circuit is used for power supply noise rejection. Pull-up resistors for the I[2] C bus design are recommended to be 2.2 k  . **==> picture [308 x 132] intentionally omitted <==** **----- Start of picture text -----**

## **Digital Interface** The VEML3328 contains a command register accessible via the I[2] C bus. All settings can be controlled via this register. The VEML3328’s I[2] C command format description for read and write operations between VEML3328 and the host is shown in Fig. 7. The white areas indicate the host activity and the gray areas indicate VEML3328’s acknowledgement of the host access activity. Note that this protocol must be followed exactly to avoid false communication on the bus. Special care should be taken for the “Read Word” format, as here a repeated start condition is a must, as indicated.

Soldering temperature: 400 °C (max.) - 1.2. Soldering time: 3 s (max.) 2. If the temperature of the method portion rises in addition to the residual stress between the leads, the possibility that an open or short circuit occurs due to the deformation or destruction of the resin increases 3. The following methods: VPS and wave soldering, have not been suggested for the component assembly 4. Cleaning method conditions: - 4.1.
