0x3F-01: ADC and Gyro Self-test Data
The module performs a self-test on the ADC and gyro at start-up. (The module
can also perform the gyro test after start-up.) If the tests are completely
successful, the gyro/ADC self-test bit in the start-up message (0x12-01) is zero. If
the bit is set to one, the host should examine the following message for diagnosis
of the errors. The ADC at fixed voltage is from the test at start-up; the “at rest”
data fields are from the most recent test. This information is not battery-backed,
and is available by query only.
