Registers 27 to 34 – Sensor Registers
Register 62 – Power Management
Type: Read only
Description:
These registers contain the gyro and temperature sensor data for the ITG-3200 parts. At any time, these values
can be read from the device; however it is best to use the interrupt function to determine when new data is
available.
Parameters:
TEMP_OUT_H/L
GYRO_XOUT_H/L
GYRO_YOUT_H/L
GYRO_ZOUT_H/L
Type: Read/Write
Description:
This register is used to manage the power control, select the clock source, and to issue a master reset to the
device.
Setting the SLEEP bit in the register puts the device into very low power sleep mode. In this mode, only the
serial interface and internal registers remain active, allowing for a very low standby current. Clearing this bit
puts the device back into normal mode. To save power, the individual standby selections for each of the gyros
should be used if any gyro axis is not used by the application.
The CLK_SEL setting determines the device clock source as follows:
On power up, the ITG-3200 defaults to the internal oscillator. It is highly recommended that the device is
configured to use one of the gyros (or an external clock) as the clock reference, due to the improved stability.
