2.1. INTRODUCTION
The STPC Industrial integrates most of the func-
tionalities of the PC architecture. Therefore, many
of the traditional interconnections between the
host PC microprocessor and the peripheral devic-
es are totally internal to the STPC Industrial. This
offers improved performance due to the tight cou-
pling of the processor core and it’s peripherals. As
a result many of the external pin connections are
made directly to the on-chip peripheral functions.

Due to the number of pins available for the pack-
age, and the number of functional I/Os, some pins
have several functions, selectable by strap option
