It is designed for the user site of the ISDN-basic access, two 64kbit/s B channels and a 16kbit/s D channel. MX97102 can be mainly divided into three portions according to their interfaces. Except these three interface functions, it also provides the LAPD controller which handles the HDLC packets of the ISDN D-channel for the associated microprocessor. The first, S/T interface controller, provides all electrical and logical functions of the S/T interface, such as S/T transceiver, activation/deactivation, timing recovery, multiframe S and Q channels, and D-channel access and priority control for communicating with remote equipments. The Second is the microprocessor interface controller which offers the registers compatible with Siemens PSB2186, provides three types of microprocessor interface, such as Motorola bus mode, Intel multiplexed mode and Intel non-multiplexed mode. The last portion is the GCI interface controller which is used to connect different voice/data application modules for local digital data exchangements.

Read/Write:A logic "HIGH" indicates a valid read operation by CPU. A logic "LOW" indicates a valid write operation by CPU.(Motorola bus mode) Write:A logic "LOW" indicates a write operation.(Intel bus mode) Data Strobe: The rising edge marks the end of a valid read or write operation (Motorola bus mode). Read:A logic "LOW" indicates a read operation.(Intel bus mode) Open Interrupt Request:The signal is a logic "LOW" when this device requests an Drain interrupt. It is an open drain output. No used. 14 NC 19,20 29,30 36 PALE 54 9 PRST 59 13 PFSC1 Address Latch Enable:A logic "HIGH" indicates an address on the address/ data bus(Multiplexed bus type only). ALE also selects the micro-processor interface type (multiplexed or non-multiplexed). I/O Reset:A logic "HIGH" on this input forces this device into reset state. The minimum pulse length is four DCL-clock periods or four ms. If the terminal specific functions are enabled,this device may also output a reset signal. O(I) Frame Sync 1:Frame sync output. Logic "HIGH" during channel 0 on the GCI interface. This pin becomes Input if Test Mode is programmed (register ADF1). O(I) Data Clock:Clock of frequency, 1536kHz output, equals to twice the GCI data rate. This pin becomes Input if Test Mode is programmed (register ADF1) O This pin output the Echo bit from the receiving line. REV. 2.5, SEP. 05, 2000 I 58 12 PDCL 62 P/N:PM.
