Gyro and Accelerometer BIT History (Latched Until Power
is Cycled or Unit is Reset)
Bits 3-8 of Mux Word Counter 1 will be latched if the
individual BIT test counter reaches 15. The test counter
is increased by 1 for a failure and then reduced by 1 if
the failure clears. Bit 2 of Mux Word Counter 1 employs
similar logic but the test counter limit is 5.

Magnetometer BIT Status
Bits 3-15 are Honeywell use only.
0=OK, 1=Failed, applies to remaining bits.
