Introduction
The purpose of this handbook is to help the system designers who implement hardware such as power
supply, clock management, reset control, boot mode setting, and debug interfaces on the development
board.
Specifically, this document provides hardware design guidelines to optimize the performance of user
applications and minimize noise transmitted from the outside to the PCB.
This handbook applies to the products with part numbers listed in Table 1.
