Processor Expert
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.
Topic
This is used to indicate a signal that is active when pulled low. For example, the RESET pin is
active when low.
A high true (active high) signal is high or a low true (active low) signal is low.
A high true (active high) signal is low or a low true (active low) signal is high.
