Appendix - B Programmer’s Sheets, Rev. 4

Freescale Semiconductor

B-3

B.1 Introduction

The following pages provide a set of reference tables and programming sheets intended to

simplify programming the 5685x. The programming sheets provide room to add the value of each

bit and the hexadecimal value for each register. These pages may be photocopied.

For complete instruction set details, please refer to Chapter 4 of the DSP56800E Reference

Manual (DSP56800ERM).

B.2 Programmers’ Sheets

Each described instruction contains notations used to abbreviate certain operands and operations

described in Table B-1. Programmers’ sheets are arranged to correspond with the chapters in this

document. The same table lists programmers’ sheets by module, the registers in each module, and

the appendix pages where the programmers’ sheets are located.

Note: Reserved bits ( ) should always be set to 0 unless otherwise stated.
