BIT Data
Description
Bit
Location
Hard Failure
An unrecoverable failure has
occurred
Bit 0
Soft Failure
A soft failure has been detected. A
soft failure can be generated by any
BIT condition designated “soft”. If
the soft failure persists for more than
2100 data packets the Hard Failure
bit is turned on and the Soft Failure
bit is permanently on.
Bit 1
Not Ready
The system is not ready to use
Bit 2
Power Fail
A power failure has been detected.
The system is on hold -up power and
is about to lose power.
Bit 3
Co mm
A serial port (user) communications
error (ex over-run, parity) has been
detected.
Bit 4
Reboot Detect
A processor reset was detected
possibly due to a watchdog timeout
or low-power setting.
Bit 5
Calibration
Table
A bad calibration table in flash
memory has been detected.
Bit 6
Turn Indicator
A turn has been detected
Bit 8
Not ready, waiting for power-up or
post sensor saturation
Bits 10,9: 11
Valid data but in initialization mode
Bits 10,9: 10
Valid data but using only gyro
integration to provide attitude output
Bits 10,9: 01
Algorithm Status
Full accuracy data
Bits 10,9: 00
Magnetometer
Cal Status
A Hardiron/Softiron calibration is
being performed.
Bit 11
Magnetometer
Cal Validity
Bad stored Hardiron/Softiron
calibration data has been detected
Bit 12
Magnetometer
Cal Performance
The Hardiron/Softiron calibration is
unsatisfactory
Bit 13
