Preface
Thank you for your continued use of Cypress products.
Read this manual and the data sheet thoroughly before using products in this family.
Purpose of This Manual/Intended Readers
This manual explains the functions and operations of this family and describes how they are used. The
manual is intended for engineers engaged in the actual development of products using this family.
For the descriptions of the Analog macro, Timer, and Communication Macro, see the respective
separate peripheral manuals.
Note:
This manual explains the configuration and operation of the peripheral functions, but does not cover
the specifics of each device in the series.
Users should refer to the respective data sheets of devices for device-specific details.
Whether a peripheral function is on board or not is dependent on product type. See data sheets for
details.
Sample Programs and Development Environment
Cypress offers sample programs free of charge for using the peripheral functions of the FM4 family.
