Assembly Language Instructions
The ’C4x assembly language instruction set supports numeric-intensive,
signal processing, and general-purpose applications. The instructions are
organized into these major groups: load-and-store, two- or three-operand
arithmetic/logical, parallel, program control, and interlocked operations
instructions. The addressing modes used with the instructions are described
in Chapter 6.
The ’C4x instruction set can also use one of 20 condition codes with any of the
10 conditional instructions, such as LDFcond. This chapter defines the
condition codes and flags.
The assembler allows optional syntax forms to simplify the assembly language
for special-case instructions. These optional forms are listed and explained.
Each of the individual instructions is described and listed in alphabetical order.
An example instruction (on pages 14-23 through 14-25) demonstrates the
special format used and explains its content.
