2. PIN DESCRIPTION
2.1. INTRODUCTION
The
STPC
Elite
integrates
most
of
the
functionalities of the PC architecture. As a result,
many of the traditional interconnections between
the host PC microprocessor and the peripheral
devices are totally internal to the STPC Elite. This
offers improved performance due to the tight
coupling
of
the
processor
core
and
these
peripherals. As a result many of the external pin
connections are made directly to the on-chip
peripheral functions.
Figure 2-1 shows the STPC Elite external
interfaces. It defines the main buses and their
function.
Table
2-1
describes
the
physical
implementation listing signals type and their
functionality. Table 2-2 provides a full pin listing
and description of pins. Table 2-7 provides a full
listing of pin locations of the STPC Elite package
by physical connection.
Note: Several interface pins are multiplexed with
other functions, refer to Table 2-4 and Table 2-5
for further details
