GND4 Note: Capacitors on the external supply AVDD should be placed as close as possible to the AVDDVCSEL and AVSSVCSEL module pins. Note: External pull-up resistor values can be found in I2C-bus specification. Pull-ups are typically fitted only once per bus, near the host. For suggested values see tables below. Note: XSHUT pin must always be driven to avoid leakage current. A pullup is needed if the host state is not known. XSHUT is needed to use HW standby mode (no I2C communication). Note: XSHUT and GPIO1 pull up recommended values are 10 kOhms. GPIO1 should be left unconnected if not used. The tables below show recommended values for pull-up and series resistors for an AVDD of 1.8 V to 2.8 V in I2C Fast mode (up to 400 kHz) and Fast mode plus (up to 1 MHz).
