10.16 Register 62 – Power Management
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.
H_RESET is used to reset the device and set the internal registers to the power-up default settings.
STBY_XG, STBY_YG, and STBY_ZG are used to place the gyros into a standby or active mode
(1=standby; 0=normal operating mode).
Setting the SLEEP bit in the register puts the device into a 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. The individual standby selections for each
of the gyros should be used if any of them are not used by the application.
The CLK_SEL setting determines the device clock source as follows:
On power up, the IMU-3000 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.
