The framer also contains a zero destuffer which is controlled via the CCR2.0 bit. In both ANSI T1.403
and TR54016, communications on the FDL follows a subset of a LAPD protocol. The LAPD protocol
states that no more than 5 ones should be transmitted in a row so that the data does not resemble an
opening or closing flag (01111110) or an abort signal (11111111). If enabled via CCR2.0, the
DS21352/552 will automatically look for 5 ones in a row, followed by a zero. If it finds such a pattern, it
will automatically remove the zero. If the zero destuffer sees six or more ones in a row followed by a
zero, the zero is not removed. The CCR2.0 bit should always be set to a one when the DS21352/552 is
extracting the FDL. More on how to use the DS21352/552 in FDL applications in this legacy support
mode is covered in a separate Application Note.

When the byte in the Receive FDL Register matches either of the two Receive FDL Match Registers (RFDLM1/RFDLM2),
SR2.2 will be set to a one and the INT will go active if enabled via IMR2.2.
