Recommended for

hardware interrupt

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).
