Instruction Set Introduction
4.4.4
A summary of the entire DSP56800E instruction set is presented in this section in tabular form. In these
tables, the instructions are broken into several different categories and then listed alphabetically.
The tables specify the operation, operands, and any relevant comments. There are separate fields for
sources and destinations of move instructions. In addition, each instruction has two fields:
Descriptions of the parallel move instruction syntax (for those operations that support them) are located at
the end of this section. See Table 4-41 on page 4-48 and Table 4-42 on page 4-49 for information on
parallel moves.
