GENERAL DESCRIPTION
W6691 consists of one D channel HDLC controller and two B HDLC controller channel access. The HDLC controller facilitates efficient access to signaling, data and voice services. It provides multiplex/non- mutiplexe 8- bit microprocessor interface. The interface is selected by external MBS selection. In addition, W6691 can be operated in TE, LT-S and LT-T mode programmed by external pin. In TE mode, W6691 provides PCM bus or GCI bus to connect with CODEC. In LT mode, it can used in NT2 application.
