1.3.1 DSP Replacement
To upgrade the DSP:
1. Use a Philips-head screwdriver to remove the 4 screws on the DSP socket U1.
2. Remove the socket top.
3. Remove the generic DSP using a chip suction device and replace it with the DSP included in
the upgrade kit. Verify that the DSP is placed in the socket securely and that the pins make
contact with the socket. Refer to Figure 1-1 for the correct orientation of the DSP.
Caution: To avoid damaging the DSP, use an anti-static wrist band when handling this
device. Using a device other than a chip suction device to lift the DSP may damage the
fine-pitched pins.
4. Replace the socket top and screw the top down.
1.3.2 68HC11 Replacement
To upgrade the 68HC11:
1. Remove the 68HC11 microcontroller from the socket U7 using a PLCC chip extractor device.
2. Replace the component with the 68HC11 included in the upgrade kit. Refer to Figure 1-1 for
the correct orientation of the 68HC11.
1.3.3 EPROM Replacement
To upgrade the EPROM:
1. Remove the EPROM from the socket U6 using a PLCC chip extractor device.
2. Replace the component with the EPROM included in the upgrade kit. Refer to Figure 1-1 for
the correct orientation of the EPROM.

SECTION 2
DEMONSTRATION INSTRUCTIONS
2.1 INTRODUCTION
This section describes the instructions on how to setup the EVM to demonstrate Dolby
DigitalTM, Dolby Pro LogicTM, DTSTM and MPEG decoding.
2.2 REQUIRED EQUIPMENT
•Dolby DigitalTM, DTSTM, or PCM source, i.e. DVD, Laserdisc, DAT, CD, VHS, etc.
•An audio amplifier driving headphones or speakers as shown on the following page in
Figure 2-1
•7-9V AC/DC power supply
2.3 DEMONSTRATION SETUP
1. Verify that the DSP, 68HC11, and EPROM have been upgraded as described in
Section 2.3.
2. Verify that the jumper modifications have been made as described in Section 1.3.4.
3. Verify that the jumper settings are correct as shown in Figure 2-2. The default jumper
setting assumes that an optical cable is used to connect the input to the EVM.
However, if using a coaxial cable, move the jumper on JP18 to pins 1-2.
4. Connect the input and output cables to the EVM as shown in Figure 2-1.
5. Apply 7-9V AC/DC to the power connector P2.

2.4.1 LCD Screen Description
The EVM’s user interface allows the user to perform the following functions:
•Activate the DSP decoder functionality
•Obtain decoder source type status information
•Select speaker configuration
•Control the master volume
•Control the individual channels volume
•Control mute and unmute
2.4.2 Decoder Activation
Once power is applied to the EVM, the Start Screen will be displayed on the LCD panel. Pressing the
S2 button (‘Go’) will activate the decoder and the LCD will display the message ‘Wait...’until a
software patch is downloaded to the DSP. After several seconds, auto-detection is activated and the
decoder type is shown on the screen.
2.4.3 Decoder Source Type
It is not necessary to reset the EVM when changing the source (AC-3, DTS, MPEG or PCM). Once
the change is made the LCD panel will automatically display the current decoder source type on the
Decoder Status Screen.
2.4.4 Speaker Configuration
Pressing the S2 button (‘Spkr’) while in the Decoder Screen gives the user control of the speaker
configuration. The default configuration for the left, right, center, surround, and subwoofer speakers
are initially set to ‘Wide’mode. However, the user has the option of changing the left, right, center,
and surround speaker configuration to ‘Narrow’mode or turning off the center, surround and
subwoofer speakers for a two-speaker configuration. Pressing the ‘Next’ button allows the user to

configure the next speaker. Table 2-1 summarizes the available speaker settings. If the source is
PCM, the DSP assumes the source is surround encoded and decodes the bitstream as Dolby Pro
Logic.
2.4.5 Volume Control
Pressing the S4 button (‘Vol’) while in the Decoder Screen gives the user control of the master and
individual channel volume. The default master and individual channel volume setting is 0 dB.
2.4.5.1 Master Volume Control
Pressing the S2 button (‘Mstr’) while in the Volume Screen gives the user control of the master
volume. In the Master Volume Screen, the master volume may be changed by pressing the S2 button
(‘V+’) to increase the volume or the S3 button (‘V-) to decrease the volume in increments of 1 dB.
The volume range is from -64 dB to +64 dB.
The master volume may be muted and unmuted by pressing the S4 button (‘Un/Mute’) and selecting
‘On’ or ‘Off’.
Pressing the S5 button (‘Home’) changes the display back to the Decoder Screen.
2.4.5.2 Individual Volume Control
Pressing the S3 button (‘Indiv’) while in the Volume Screen gives the user control of the individual
channel volume. In the Individual Channel Volume Screen, the individual channel volume may be
changed by pressing the S2 button (‘V+’) to increase the volume or the S3 button (‘V-) to decrease
