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.

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

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
