1.3 State of the Art Development Environment
Processor ExpertTM (PE) provides a Rapid Application Design (RAD) tool that combines easy-to-use
component-based software application creation with an expert knowledge system.
The Code Warrior Integrated Development Environment is a sophisticated tool for code navigation,
compiling, and debugging. A complete set of evaluation modules (EVMs) and development system cards
will support concurrent engineering. Together, PE, Code Warrior and EVMs create a complete, scalable
tools solution for easy, fast, and efficient development.
1.4 Product Documentation
The four documents listed in Table 1-1 are required for a complete description of and proper design with
the 56857. Documentation is available from local Freescale distributors, Freescale Semiconductor sales
offices, Freescale Literature Distribution Centers, or online at www.freescale.com.

OVERBAR
This is used to indicate a signal that is active when pulled low. For example, the RESET pin is
active when low.
“asserted”
A high true (active high) signal is high or a low true (active low) signal is low.
“deasserted”
A high true (active high) signal is low or a low true (active low) signal is high.
