14-CHANNEL T1/E1/J1 SHORT-HAUL LINE INTERFACE UNIT
The Microprocessor Interface section supports communication between the local microprocessor (µP) and the
LIU. The XRT83SL314 supports an Intel asynchronous interface, Motorola 68K asynchronous, and a Motorola
Power PC interface. The microprocessor interface is selected by the state of the µPTS[2:0] input pins.
Selecting the microprocessor interface is shown in Table 14.
The XRT83SL314 uses multipurpose pins to configure the device appropriately. The local µP configures the
LIU by writing data into specific addressable, on-chip Read/Write registers. The microprocessor interface
provides the signals which are required for a general purpose microprocessor to read or write data into these
registers. The microprocessor interface also supports polled and interrupt driven environments. A simplified
block diagram of the microprocessor is shown in Figure 38.
