Chapter 7
Graphical Configuration Tool
7.1
Introduction
This section describes the functionality of the Graphical Configuration Tool (GCT) for the
56F8xxx family of Digital Signal Controllers. The Graphical User Interface (GUI), settings, file
formats and the import/export rules will be described. The features and functionality of on-chip
peripheral modules are described in the 56F8300 Peripheral User Manual (83xx and 81xx
devices) and 56F8000 Peripheral Reference Manual (80xx devices).
GCT enables to create a static configuration of on-chip peripheral modules in an easy-to-use
graphical environment. A graphical representation exists for all control bits or registers of each
peripheral module. On the other hand, the status bits or bit-fields and other run-time-only registers
are not covered by GCT. Typically, the run-time registers are accessed indirectly by the "ioctl"
calls described in previous chapters.
