About This Manual
This document describes the hardware and software installation and setup. It
explains operation and EPROM programming
The manual assumes that you have set up the Windows operating environ-
ment and that you are familiar with the basic terminology and procedures for
using Microsoft Windows. To set up Windows or review basic Windows in-
formation, see your Windows documentation.
How to Use This Manual
This document contains the following chapters:
-
Chapter 1 Installation and Setup

-
Chapter 3 Hardware
-
Chapter 4 EPROM Programming
Notational Conventions
This document uses the following conventions.
-
Program listings, program examples, and interactive displays are shown
in a special typeface similar to a typewriter’ s. Examples use a bold
version of the special typeface for emphasis; interactive displays use a
bold version of the special typeface to distinguish commands that you
enter from items that the system displays (such as prompts, command
output, error messages, etc.).
Here is a sample program listing:
0011 0005 0001 .field 1, 2
0012 0005 0003 .field 3, 4
0013 0005 0006 .field 6, 3
0014 0006 .even

Here is an example of a system prompt and a command that you might
enter:
C: csr –a /user/ti/simuboard/utilities
-
In syntax descriptions, the instruction, command, or directive is in a bold
typeface font and parameters are in an
italic typeface
. Portions of a syntax
that are in bold should be entered as shown; portions of a syntax that are
in
italics
describe the type of information that should be entered. Here is
an example of a directive syntax:
.asect
section name
,
address
.asect is the directive. This directive has two parameters, indicated by
sec-
tion name
and
address
. When you use .asect, the first parameter must be
an actual section name, enclosed in double quotes; the second parameter
must be an address.
-
Square brackets ( [ and ] ) identify an optional parameter. If you use an
optional parameter, you specify the information within the brackets; you
don’t enter the brackets themselves. Here’s an example of an instruction
that has an optional parameter:
LALK
16–bit constant [, shift]
The LALK instruction has two parameters. The first parameter,
16-bit con-
stant
, is required. The second parameter ,
shift
, is optional. As this syntax
shows, if you use the optional second parameter , you must precede it with
a comma.
Square brackets are also used as part of the pathname specification for
VMS pathnames; in this case, the brackets are actually part of the path-
name (they are not optional).
-
Braces ( { and } ) indicate a list. The symbol | (read as
or
) separates items
within the list. Here’s an example of a list:
{ * | *+ | *– }
This provides three choices: *, *+, or *–.
Unless the list is enclosed in square brackets, you must choose one item
from the list.
-
Some directives can have a varying number of parameters. For example,
the .byte directive can have up to 100 parameters. The syntax for this di-
rective is:
.byte
value
1
[, ... , value
n
]
This syntax shows that .byte must have at least one value parameter , but
you have the option of supplying additional value parameters, separated
by commas.
The information in a caution or a warning is provided for your protection.
Please read each caution and warning carefully.

1) Using the 25-pins SUB-D connector, connect the programming adapter to
the parallel port (LPT1–LPT3) of the PC.
2) Connect an external power supply to the programming adapter. The
voltage of the power supply must be between 14 V and 20 V dc and must
provide a minimum of 200 mA of power . The center terminal of the supply
connector at the programming adapter is the plus pole.
3) The red LED on the programming adapter lights if the power supply is
properly connected. If the LED does not light and the power supply is
properly connected check the F1 fuse on the programming adapter printed
wire board (PWB).
4) The MSP430 devices, in a socket or on a PWB, should be connected to
the programming adapter through the 9-pin cable.
If only the device itself is connected, the programming adapter provides a
supply voltage VCC of
5 V at pin 6 of the 9-pin SUB-D connector or pin 2
of the 14-pin connector. The signal name is VCC_MSP.
If the device is supplied externally, as in the case of in-circuit programming,
the external VCC should be connected to pin 7 of the 9-pin SUB-D
connector or pin 4 of the 14-pin connector. This configuration ensures that
the voltage level of the programming signals is adjusted to the external
VCC. The signal name is MSP_VCC_IN.
Note:
Almost all standard power supplies yield a higher output voltage than
specified. Most universal 12-V power supplies can be used as the external
power supply for the programming adapter.

A common way to program an MSP430 device is by selecting the file with
the appropriate data from the Program Device dialog box (Figure 2–1) and
selecting the Parallel Port LPTx button. The device configuration and
memory type are selected automatically according to the connected de-
vice. Clicking the Program button starts the programming operation.
Table 2–1 describes the function buttons for different options and combina-
tions for the MSP430 Program Device dialog box.
Table 2–1.MSP430 Function Buttons and Descriptions
Button Name Description
Program An object code is programmed to the on-chip memory without
Verify and without Blow. The code protection fuse is left intact.
Program with Verify Each section is verified after it is programmed.
Program with Blow The code protection fuse is blown after the complete object
code, with or without Verify, is programmed. This action
irreversibly disables future access (read or programming) to
the on-chip memory.
Verify A verification of the selected object file and the program
memory contents of the device is performed.
Erase Check An erase check is performed depending on the values
entered in the Range for Erase Check/Readout field.
Erase Check by file Only the memory locations corresponding to the selected
object file are checked.
Reset A software reset of the chip is generated.
Blow Fuse Any access (read or programming) to the on-chip memory is
disabled irreversibly.
Read Out†The content of the connected device to the file selected in the
Filename field is read out. The desired memory range is
selected in the Range for Erase Check/Readout field.
Help Help is available for programming MSP430 devices, and for
using command buttons, selectors, and the used object file
format.
†Some older devices without security fuses are read-protected.

3.1 Specifications
The specifications for the MSP430 hardware are shown in Table 3–1.
Table 3–1.MSP430 Hardware Specifications
Temperature range 10°C–45°C
Humidity 40%–70%
Power supply 14 V–20 V, 200 mA minimum
Dimensions (W)140 mm × (H)30 mm × (D)70 mm
3.2 Basic Hints
The basic hints useful for programming MSP430 devices or MSP430 devices
on printed wire boards (PWB).
-
All VCC pins of an MSP430 device are tied together and connected to the
most positive terminal of the supply.
-
All VSS pins of an MSP430 device are tied together and connected to the
most negative terminal of the supply.
-
The interface should supply the MSP430 with proper conditions according
to the device datasheet in terms of current, voltage levels, and timing con-
ditions.
-
MSP430x3xx family: Six interconnections are needed as minimum:
TMS, TCK, TDI/VPP, TDO/TDI, VSS, and XOUT.
-
MSP430x11x family: Seven interconnections are needed as minimum:
TMS, TCK, TDI, TDO/TDI, VSS, Test/VPP, and
XOUT.
-
Short cables to interconnect the interface to the MSP430 device or PWB;
less than 20 cm is recommended.
-
Ensure low-impedance interconnections: Especially for the path of the
programming and fuse blow voltage – TDI/VPP (MSP430x3xx family) or
Test/VPP (MSP430x11x family).
-
When a device with a transparent window is programmed, the window
should be already covered with an opaque label while the device is
programmed. Since ambient light contains the correct wavelength for
erasure, keep the transparent window covered after the device is
programmed.

3.3 Programming Adapter Target Connector Signals
The target connector signals for the programming adapter ensure
communication between programming adapter and MSP430 devices and
supply low energy to systems without extra supply sources.
Figure 3–1 and Figure 3–2 show the target connector signals for the program-
ming adapter.

Hardware
Table 3–2.Target Connector Signal Functions (Continued)
Signal/Terminal Name Required Function/Comment
GND Mandatory GND is the most negative terminal.
VCC_MSP (see Note 1) Defined by application Voltage source is used with MSP430 devices or PWBs.
The voltage is ~ 5 V when MSP_VCC_IN is open,
or the voltage follows the level applied to MSP_VCC_IN.
MSP_VCC_IN
(see Note 1) Defined by application Used with function of VCC_MSP.
XOUT Mandatory Signal supplies the MSP430 system with clock signals.
RST/NMI (see Note 2) Signal connects to a pullup resistor to VCC_MSP to
prevent unexpected reset conditions.
Test/VPP (see Note 3) Mandatory Signal used with MSP430x11x devices to select pin or
JTAG function or to apply VPP.
Notes: 1) The signals VCC_MSP and VCC_MSP_IN may not be connected.
2) The RST/NMI signal is valid for MSP–PRG430A and MSP–PRG430B.
3) The Test/VPP signal is valid for MSP–PRG430C, and MSP-PRG430D.
The output signal levels of the programming adapter depend on the conditions
at the MSP_VCC_IN line as indicated in Table 3–3.
-
The RST/NMI terminal of the device must be high; otherwise the access
to the device via JTAG system may fail.
-
The programming procedure (handling of the SW) is descibed in the
manual that was included with the programming adapter package.
-
The connections from the MSP430 terminals must follow EMI rules; such
as short lines and ground planes. If TMS line receives one negative pulse
by EMI strike, the fuse current is activated (with fuse version 1.0). The fuse
current flows from TDI/VPP pin to GND (or VSS).

Notes: 1) ~5V*[Rext/(Rext+100 kΩ)] 5 V are as accurate as the TL750LC05CLP (in the PRG430x).
2) The signal is either RST/NMI or Test/VPP. Test/VPP is needed in the ’1 1x’s shared JT AG pin implementation. RST/
NMI is not always needed. During JTAG access the RST/NMI terminal must be high. If not, no access is possible,
and the JTAG function is reset.

3.7.1 Upgrade of MSP-PRG430B to MSP-PRG430C
The MSP-PRG430B programming adapter hardware can easily be upgraded
to the programming adapter version C. The following modifications describe
how an MSP-PRG430B can be upgraded to a MSP-PRG430C:
-
Open the case of the programmer by removing the screw that is located
in the center of the top surface, under the label.
-
Remove resistor R36.
-
Add R37. This resistor’s value is 0 Ω.
-
Add a capacitor of 47 pF from base of T3 to 5 V.
Use the correct software version after the upgrade. Make sure that the target’s
RST/NMI pin is not connected to pin 8 of the 14-pin connector. After the modifi-
cation, the Test/VPP signal is applied to this signal line. If the pullup resistor
of the MSP-PRG430B was used to keep the RST/NMI terminal high, the target
must be modified for the RST/NMI terminal to remain high.
Note:
The upgrades for MSP-PRG430B to MSP-PRG430D and for MSP-
PRG430C to MSP-430D are described in paragraph 3.8.1 and 3.8.2.

The circuit diagrams in Figure 3–1 1 show the connections required to program
the MSP430P313DL device with programming adapter PRG430B in a sepa-
rate socket. Since the device is not connected to a power supply in this configu-
ration, the necessary supply comes from the PRG430B.
