MICROPROCESSOR INTERFACE BLOCK
The Microprocessor Interface section supports communication between the local microprocessor (μP) and the
LIU. The XRT83VSH314 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 13
.
The XRT83VSH314 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 32
.
