Reading this register returns the current state value of the OOF, OOSMF and
OOCMF FRMR framing statuses.
OOF:
The OOF bit is a logic one when basic frame alignment has been lost. The
OOF bit goes to a logic zero once frame alignment has been regained.
OOSMF:
The OOSMF bit is a logic one when the signalling multiframe alignment has
been lost. The OOSMF bit becomes a logic zero once signalling multiframe
has been regained.
OOCMF:
The OOCMF bit is a logic one when the CRC multiframe alignment has been
lost. The OOCMF bit becomes a logic zero once CRC multiframe has been
regained.
