About This Manual
The purpose of this user’s guide is to assist you, the hardware or software en-
gineer, in developing applications using the TMS320F/C240,F/C24x digital
signal processors (DSPs). This book provides CPU, hardware, and instruction
set details for these devices, and explains the DSP core that is common to all
TMS320F/C24x DSP controllers; and consequently, is common to the devices
described in this manual.
Throughout this book, the TMS320F/C240,F/C24x devices are generally re-
ferred to as ’24x.
For information about ’24x peripherals, see
TMS320F/C240 DSP Controllers,
Peripheral Library and Specific Devices
(literature number SPRU161), or
TMS320F243/F241/C242 DSP Controllers System and Peripherals Refer-
ence Guide
(literature number SPRU276).
Notational Conventions
This document uses the following conventions:
- Program listings and program examples are shown in a special type-
face.
Here is a segment of a program listing:
OUTPUT LDP #6 ;select data page 6
BLDD #300, 20h ;move data at address 300h to 320h
RET
- Hexadecimal numbers are represented with a lowercase letter
h
following
the number. For example, 7400h or 743Fh.
- In syntax descriptions, the instruction is in a bold typeface and
parameters are in an
italic typeface
. Portions of a syntax in bold must be
entered as shown; portions of a syntax in
italics
describe the type of
information that you specify. Here is an example of an instruction syntax:
BLDD
source, destination
BLDD is the instruction and has two parameters,
source
and
destination
.
When you use BLDD, the first parameter must be an actual data memory

source address and the second parameter must be a destination address.
A comma and a space (optional) must separate the two addresses.
- Square brackets, [ ], identify an optional parameter. If you use an optional
parameter, specify the information within the brackets; do not type the
brackets themselves. When you specify more than one optional parame-
ter from a list, you separate them with a comma and a space. Here is a
sample syntax:
BLDD
source
,
destination
[, AR
n
]
BLDD is the instruction. The two required operands are
source
and
destination
, and the optional operand is AR
n
. AR is bold and
n
is italic; if
you choose to use AR
n
, you must type the letters A and R and then supply
a chosen value for
n
(in this case, a value from 0 to 7). Here is an example:
Information About Cautions
This book contains cautions.
This is an example of a caution statement.
A caution statement describes a situation that could potentially
damage your software or equipment.
