There is an optional transparent mode of operperformed. ation in which no HDLC processing is performed on Frame sync (FS) allows a slot-select feature to user data. The device communicates with the system microprocessor as a memory-mapped peripheral and access an individual time slot in any TDM data is controlled by reading and writing 19 internal regisstream (e.g.
