Chapter 6: Board Interfaces Reference
6.1 INTRODUCTION
This chapter describes the connectors and headers that allow you to connect the CS89712
Development Board to your host PC and to connect the board to a variety of peripheral devices. It
also describes the jumpers and settings that allow you to control the operating mode of these
interfaces. Refer to the board layout in
Figure 4-3, “Layout of CS89712 Development Board with
Major Board Components Identified,”
for the exact location of the CS89712 Development Board
components.
6.2 LOCATION OF MAJOR CONNECTORS DISCUSSED IN THIS CHAPTER
Table 6-1
describes the purpose of the connectors on the CS89712 Development Board and how they
are labeled on the board.
6.3 MAJOR INTERFACES
