8 Application Information
8.1 Sleep Mode
The target is to provide the possibility to reduce the total current consumption. No output signal will be provided when the IC is in sleep mode.
Enabling or disabling sleep mode is done by sending the SLEEP or WAKEUP commands via. the SSI interface. Analog blocks are powered
down with respect to fast wake up time.
8.2 SSI Interface
The setup for the device is handled by the digital interface. Each communication starts with the rising edge of the chip select signal. The
synchronization between the internal free running analog clock oscillator and the external used digital clock source for the digital interface is
done in a way that the digital clock frequency can vary in a wide range.
