MICROPROCESSOR INTERFACE BLOCK
The Microprocessor Interface section supports communication between the local microprocessor (μP) and the
LIU. The XRT75L06D 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
.
