TEI1
TEI1 ... Terminal Endpoint Identifier
In all message transfer modes except in transparent modes 0, 1 and extended
transparent mode, TEI1 is used for address recognition. In the case of a two-byte
address field, it contains the value of the first programmable Terminal Endpoint Identifier
according to the ISDN LAPD-protocol.
In non-auto-modes with one-byte address field, TEI1 is a command address, according
to X.25 LAPB.
EA
This bit is set to ’1’ according to HDLC/LAPD.

interrupt in order to determine the number of bytes to be read from the RFIFO, and
the total message length. The contents of the registers are valid only after an RME
or RPF interrupt, and remain so until the frame is acknowledged via the RMC bit
or RRES.
