Supported features
Operation modes
Power Down

Measurement
Sensors are factory calibrated. Trimmed parameters are sensitivity, offset, internal current &
voltage references and frequency of the internal oscillator. Calibration parameters will be read
automatically from the internal non-volatile memory during sensor startup.
Supported features are listed in Table 1 below.

In Power Down (PD) mode device's volatile registers keep their contents and the current
consumption is minimized. Power down mode is the default mode after start up.
Stand By (SB) mode can be used to start-up the sensor quickly. In SB mode only the primary
resonator loop is on with reduced bias current while the other blocks are off.
In Measurement mode (Meas) the sensor offers angular rate information via the digital SPI/I
interface. Interrupt can be activated via INT-pin, when each xyz-angular rate sample is ready to be
read.
Measurement bandwidth can be selected through register command.
The CMR3000 has a dedicated output pin (INT) to be used as the interrupt for the master
controller. Interrupt conditions can be activated and deactivated via the SPI or I
