10 Register Description
This section details each register within the InvenSense IMU-3000 gyroscope. Note that any bit that is not
defined should be set to zero in order to be compatible with future InvenSense devices.
The register space allows single-byte reads and writes, as well as burst reads and writes. When performing
burst reads or writes, the memory pointer will increment until either (1) reading or writing is terminated by the
master, or (2) the memory pointer reaches registers 57 or 60.
10.1 Register 0 – Who Am I
10.2 Registers 12 to 17 – Gyro Offsets
Type: Read/Write
Description:
This register is used to verify the identity of the device.
Parameters:
ID
0
The Power-On-Reset value of Bit6: Bit1 is 110 100.
The Power-On-Reset value of Bit7 is 0.
Type: Read/Write
Description:
These registers are used to remove DC bias from the sensor outputs. The values in these registers
are subtracted from the gyro sensor values before going into the sensor registers (see registers 29 to
34).
Parameters:
X_OFFS_H/L
Y_OFFS_H/L
Z_OFFS_H/L
