Line Echo Cancellation Adaptation Start. The LEC-ADAPT bit is only
evaluated if the LEC-EN is changed from 0 to 1.
To initialize the LEC coefficients to 0 requires the LEC-ADAPT bit set
to 0 followed by the LEC-EN bit changed from 0 to 1.
It is not possible to reset the LEC coefficients to 0 while the LEC is
running. The LEC has to be disabled first by setting bit LEC-EN to 0 and
then it is necessary to enable the LEC again (LEC-EN = 1, LEC-ADAPT
= 0). If valid coefficients from a former LEC adaptation are present in
the RAM, it is possible to activate the LEC with this coefficents by
setting bit LEC-ADAPT to 1.
It is also possible to read out adapted coefficients from the LEC for
external storage and to reuse these coefficients as a start up value for
the next connection (see the available Application Notes).

Low-level framing: all data for CID transmissions must
be written to the CID Buffer including channel seizure
and mark sequence, start and stop bits.
High-level framing: channel seizure and mark sequence
as well as start and stop bits are automatically inserted
by the SLICOFI-2x. Only transmission bytes from the
Data Packet (see
CIS buffer.
