About This Book
This guide provides detailed information about the MC13192 Sensor Applications Reference Design
(SARD). The SARD provides all the components to evaluate and use an MC13192. It is intended to allow
a system engineer or software developer to gain an understanding of the MC13192 and its protocol.
Audience
The guide is intended for software and system engineers who are developing their products or software
applications making use of the MC13192 to achieve wireless connectivity capability.
It is assumed that the reader has a good working knowledge of general-purpose microcontrollers (MCU).
Organization
The book is divided into 1 chapter and 1 appendix.
Chapter 1 introduces the MC13192 Sensor Applications Reference Design (SARD) functionality and
features.
Appendix A provides figures of the SARD printed circuit board.
Conventions
This section names, describes, and defines the conventions used in the book. This document uses the
following conventions:
• OVERBAR is used to indicate a signal that is active when pulled low: for example, RESET
.
• Logic level one is a voltage that corresponds to Boolean true (1) state.
• Logic level zero is a voltage that corresponds to Boolean false (0) state.
•To set a bit or bits means to establish logic level one.
•To clear a bit or bits means to establish logic level zero.
•A signal is an electronic construct whose state conveys or changes in state convey information.
•A pin is an external physical connection. The same pin can be used to connect a number of signals.
• Asserted means that a discrete signal is in active logic state.
— Active low signals change from logic level one to logic level zero.
— Active high signals change from logic level zero to logic level one.
• Negated means that an asserted discrete signal changes logic state.
— Active low signals change from logic level zero to logic level one.
— Active high signals change from logic level one to logic level zero.
• LSB means least significant bit or bits, and MSB means most significant bit or bits. References to
low and high bytes or words are spelled out.
