4.6.2 Software-Related Error Conditions
Possible indications of software-related errors are given below in Table 4-8:
Table 4-8: Software-Related Error Indications
Register Name Address Error Indication
EventStatus 0x35 [1] 1 = Error.
SensorStatus 0x36
[0] MagNACK. 1 = NACK from magnetometer
[1] AccelNACK. 1 = NACK from accelerometer
[2] GyroNACK. 1 = NACK from gyroscope
[4] MagDeviceIDErr. 1 = Unexpected DeviceID from
magnetometer
[5] AccelDeviceIDErr. 1 = Unexpected DeviceID from
accelerometer
[6] GyroDeviceIDErr. 1 = Unexpected DeviceID from
gyroscope.
SentralStatus 0x37 [3] 1 = Idle. SENtral in Initialized State.
ErrorRegister 0x50 Non-zero value indicated an error. See Table 4-9 .
RAMVersion 0x72, 0x73 Unexpected Configuration File revision level.
If the ErrorRegister indicates a non-zero value, then the value provides additional
information on the sensor that is causing a problem, as given in Table 4-9.

Value Error Condition Response
0x00 No error
0x80 Invalid sample rate selected Check sensor rate settings.
0x30 Mathematical Error Check for software updates
0x21 Magnetometer initialization failed This error can be caused by a wrong
driver, physically bad sensor
connection, or incorrect I

C device
address in the driver
0x22 Accelerometer initialization failed
0x24 Gyroscope initialization failed
0x11 Magnetometer rate failure
This error indicates the given sensor
is unreliable and has stopped
producing data. 0x12 Accelerometer rate failure
0x14 Gyroscope rate failure
If the RAMVersion register values do not correspond to the expected Configuration File
revision level, as given in Table 4-10, certain features or functions that are expected to be
