Parallel Microprocessor Interface Block
The Parallel Microprocessor Interface section supports communication between the local microprocessor (μP)
and the LIU. The XRT83VSH28 supports an Intel asynchronous interface, Motorola 68K asynchronous, and an
Intel/Motorola interface. The microprocessor interface is selected by the state of the μPTS[1:0] input pins.
Selecting the microprocessor interface is shown in
Table 10
.
The XRT83VSH28 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
