If the SensorStatus register indicates a non-zero value, then the value provides additional
information on the sensor that is causing a problem, as given in Table 5-11.
Table 5-11: SensorStatus Register Values
Register Name Address Error Indication
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.
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 5-12.

If the RAMVersion register values do not correspond to the expected Configuration File
revision level, as given in Table 5-13, certain features or functions that are expected to be
available may not be available, or they may not function as expected. This normally can
be remedied by generating the latest Configuration File revision level using the SENtral
