MICROPROCESSOR INTERFACE BLOCK
The Microprocessor Interface section supports communication between the local microprocessor (μP) and the
LIU. The XRT73L06 supports a parallel interface asynchronously or synchronously timed to the LIU. The mi-
croprocessor interface is selected by the state of the Pmode input pin. Selecting the microprocessor interface
mode is shown in Table 11.
The local μP configures the LIU by writing data into specific addressable, on-chip Read/Write registers. The
μP provides the signals which are required for a general purpose microprocessor to read or write data into
these registers. The μP also supports polled and interrupt driven environments. A simplified block diagram of
the microprocessor is shown in Figure 34.
