{Pass/Fail, Unmasked/Masked}
Indicates that the demod is unable to lock to a signal.
{Pass/Fail, Unmasked/Masked}
Indicates that the Framing Unit is unable to find the
expected framing pattern.

Indicates that a Doppler Buffer underflow has occurred.
{Pass/Fail, Unmasked/Masked}
Indicates that the Doppler Buffer is about to underflow.
{Pass/Fail, Unmasked/Masked}
Indicates that the Doppler Buffer is about to overflow.
{Pass/Fail, Unmasked/Masked}
Indicates that a Doppler Buffer overflow has occurred.
{Pass/Fail, Unmasked/Masked}
Indicates that there is no Rx Data activity.
{Pass/Fail, Unmasked/Masked}
Indicates that AIS has been detected in the receive
satellite data stream.
{Pass/Fail, Unmasked/Masked}
Indicates if drop/insert data is frame locked.
{Pass/Fail, Unmasked/Masked}
Indicates if drop/insert data has multiframe lock.
{Pass/Fail, Unmasked/Masked}
