The TLV320AIC12KEVMB-K/14KEVMB-K motherboard (the USB-MODEVM Interface board) supplies
power to J3 of the TLV320AIC12KEVMB/14KEVMB. Power for the motherboard is supplied either through
its USB connection or via terminal blocks on that board.
4.1
Stand-Alone Operation
When used as a stand-alone EVM, power can be applied to J3 directly. The user must be sure to
reference the supplies to the appropriate grounds on that connector.
CAUTION
Verify that all power supplies are within the safe operating limits shown on the
TLV320AIC12K/14K data sheet before applying power to the EVM.
4.2
USB-MODEVM Interface Power
The USB-MODEVM Interface board can be powered from several different sources:
• USB
• 6VDC–10VDC AC/DC external wall supply (not included)
• Lab power supply
When powered from the USB connection, JMP6 should have a shunt from pins 1–2 (this is the default
factory configuration). When powered from 6V-10VDC, either through the J8 terminal block or the J9
barrel jack, JMP6 should have a shunt installed on pins 2-3. If power is applied in any of these ways,
onboard regulators generate the required supply voltages and no further power supplies are necessary.
If lab supplies are used to provide the individual voltages required by the USB-MODEVM Interface, JMP6
should have no shunt installed. Voltages are then applied to J2 (+5VA), J3 (+5VD), J4 (+1.8VD), and J5
(+3.3VD). The +1.8VD and +3.3VD can also be generated on the board by the onboard regulators from
the +5VD supply; to enable this configuration, the switches on SW1 need to be set to enable the
regulators by placing them in the ON position (lower position, looking at the board with text reading
right-side up). If +1.8VD and +3.3VD are supplied externally, disable the onboard regulators by placing
SW1 switches in the OFF position.
Each power supply voltage has an LED (D1-D7) that lights when the power supplies are active.

Installation
Ensure that the TLV320AIC12KEVMB/14KEVMB is installed on the USB-MODEVM Interface board,
aligning J1, J2, J3, J4, J5 with the corresponding connectors on the USB-MODEVM.
Place the CD-ROM into your PC CD-ROM drive. Locate the Setup program on the disk, and start it. The
Setup program will install the TLV320AIC12K/14K Evaluation Tool software on your PC.
The NI-VISA Runtime installer is embedded to the TLV320AIC12K/14K Evaluation Tool installer. This
software allows the program to communicate with the USB-MODEVM.
When the installation completes, click Finish on the TLV320AIC12K/14K Evaluation Tool installer window.
You may be prompted to restart your computer.
When installation is complete, attach a USB cable from your PC to the USB-MODEVM Interface board. As
configured at the factory, the board will be powered from the USB interface, so the power indicator LEDs
and the 'USB ACTIVE' LED on the USB-MODEVM should light.
The Found New Hardware Wizard will show up on the screen. Select the 'No, not this time' radio button
and click 'Next >'. Select 'Install the software automatically (Recommended)' and click 'Next >'. If the
driver installs correctly the message: 'The wizard has finished installing the software for: AIC12K/14K
EVM' should appear. Click 'Finish'. The AIC12K/14K EVM driver should now be installed. The device
should now appear on the Device Manager as 'NI-VISA USB Devices>AIC12K/14K EVM' and as 'Sound,
video and game controllers>USB Audio Device'.
Once the device drivers are installed launch the TLV320AIC12K/14K Evaluation Tool software on your
PC, located on the computer's desktop or in 'Start>Programs>Texas Instruments'.
The software should automatically find the TLV320AIC12K/14K, and a screen similar to the one in
Figure 2 should appear.

USB-MODEVM Interface Board
The simple diagram shown in Figure 1 shows only the basic features of the USB-MODEVM Interface
board. The board is built around a TAS1020B streaming audio USB controller with an 8051-based core.
The board features two positions for modular EVMs, or one double-wide serial modular EVM may be
installed.
Since the TLV320AIC12KEVMB/14KEVMB is a double-wide modular EVM, it is installed with connections
to both EVM positions, which connects the TLV320AIC12K/14K digital control interface to the I2C port
realized using the TAS1020B, as well as the TAS1020B digital audio interface.
In the factory configuration, the board is ready to use with the TLV320AIC12KEVMB/14KEVMB. To view
all the functions and configuration options available on the USB-MODEVM board, see the USB-MODEVM
Interface Board schematic in Appendix B.

Indicators and Main Screen Controls
Figure 2 illustrates the indicators and the main screen controls near the top of the software screen display,
and a large tabbed interface below. This section discusses the controls above this tabbed section.
At the top left of the screen is an Interface indicator. The TLV320AIC12K/14K has an I2C interface. The
indicator is lit after the program begins. Below the Interface indicator is the Device Connected indicator.
The TLV320AIC12K/14K Evaluation Tool detects whether or not the TLV320AIC12KEVMB-K/14KEVMB-K
is present. If the device is unplugged from the USB port or if the device driver is not installed properly, the
Device Connected indicator will turn red. Otherwise, it will turn green.
To the right of the Interface indicator is a group box called Firmware. This box indicates the product
identification of the USB device, so AIC12K/14K EVM should be displayed in the box labeled Located
On:. The version of the firmware appears in the Version box below this.
To the right, the next group box contains controls for resetting the TLV320AIC12K/14K. A software reset
can be done by writing to a register in the TLV320AIC12K/14K; the writing is accomplished by pushing the
button labeled Software Reset. This button also resets to the default I2C address and refreshes the GUI's
register table and controls/indicators by reading all registers. The TLV320AIC12K/14K also may be reset
by toggling a GPIO pin on the USB-MODEVM, which is done by pushing the Hardware Reset button.
CAUTION
In order to perform a hardware reset, the RESET jumper (W7) must be installed
and SW2-7 on the USB-MODEVM must be turned OFF. Failure to do either of
these steps results in not generating a hardware reset or causing unstable
operation of the EVM, which may require cycling power to the USB-MODEVM.
The ADC Overflow and DAC Overflow indicators light when the overflow flags are set in register 1 of the
TLV320AIC12K/14K. These indicators, as well as the other indicators on this panel, update only when
writing or reading registers, on resets or by pushing the Refresh button. The Indicator Updates and
Control Updates buttons enable/disable updates of indicators and controls, respectively.
6.6
Information Tab
The information tab (Figure 3) shows information for two TLV320AIC12KEVMB-K/14KEVMB-K hardware
configurations.
The USB-MODEVM Audio Interface Configuration allows audio data and I2C communication between
the host computer and the TLV320AIC12K/14K. SW2 on the USB-MODEVM must be configured as
shown in the left section of Figure 3.

Additionally, the operating system's audio device must be configured as AIC12K/14K EVM (see Figure 4).
The External Audio Interface Configuration only allows I2C communication between the host computer
and the TLV320AIC12K/14K. In this configuration, the TLV320AIC12K/14K can transmit and receive audio
data to/from an external PCM device or DSP. SW2 on the USB-MODEVM must be configured as shown in

Device Controls Tab
The Device Controls Tab (Figure 6) contains six enumerated Control Registers sub tabs with controls
for all six registers of the TLV320AIC12K/14K, a register table at the bottom of the tab, several controls
and an indicator at the right of the tab. The 8-bit I2C Address indicator shows the current I2C address.
The Device Position control lets the user select a specific codec on a master-slave chain to write to or
read from. The TLV320AIC12KEVMB-K/14KEVMB-K is configured as a stand-alone slave, so the device
position must be set to zero. The Program Device button, when pushed, programs the register
corresponding only to the selected Control Registers sub tab. The register table holds the current
register values in hexadecimal and binary format. The Register Dump to File button dumps the current
register values to a spreadsheet. Please refer to the TLV320AIC12K/14K datasheet for further details on
control register content.

Control Register 1 Tab
The Transfer Mode control lets the user select between continuous data transfer mode or programming
mode. In the continuous data transfer mode, only audio data is sent and received through the serial audio
bus. In the programming mode, control data is sent and received through the serial audio bus. The Data
Format Mode, if set to 15 bits + 1, allows the codec to run in continuous mode and switch to
programming mode by setting the LSB of DIN to 1 to send control data. The USB-MODEVM Audio
Interface Configuration currently supports continuous and 16-bits audio data transfers. The Mic Bias sets
the voltage of the BIAS pin to 2.35V or 1.35V. The Selected Filter button allows the user to select
between an FIR filter or an IIR filter for the decimation/interpolation low-pass filter. The Loopback
switches toggle the analog or digital loopback on and off. The indicator below each switch will light when
on only if the register data sent by pressing the Program Device button is acknowledged.

The Turbo Mode control (Figure 8) sets the SCLK frequency to 16×FS×(number of devices)×mode or
MCLK÷P, where number of devices is the number of codecs in cascade (default=1) and the mode is 1 for
continuous data transfer mode and 2 for programming mode. The Host Port Control can be used to
assign different functions to the SDA pin or to set SCL and SDA for I2C or S2C. When using the
USB-MODEVM Audio Interface Configuration the Host Port Control must be set to SDA/SCL are I2C
interface pins.
If the host interface is not needed, the two pins of SCL and SDA can be programmed to become
general-purpose I/Os. If selected to be used as I/O pins, the SDA and SCL pins become output and input
pins respectively, determined by D1 and D0. SDA can then be set to 1 or 0 by toggling the General
Purpose Output control.
The Decimation/Interpolation filter bypass button bypasses the filters selected in register 1. This can be
useful when using a DSP to apply such filters. The I2C Base Address control allows the user to select the
first three bits (MSB first) of the device's 7-bit I2C address. The last 4 bits of the address will depend on
the automatic cascade detection (ACD) feature of SMARTDM™, which sets the device position.

A simple scripting language controls the TAS1020 on the USB-MODEVM from the LabView™-based PC
software. The main program controls, described previously, do nothing more than write a script which is
then handed off to an interpreter that sends the appropriate data to the correct USB endpoint. Because
this system is script-based, provision is made in this tab for the user to view the scripting commands that
are created as the controls are manipulated, as well as load and execute other scripts that have been
written and saved (see Figure 13). This design allows the software to be used as a quick test tool or to
help provide troubleshooting information in the rare event that the user encounters a problem with this

by pressing the Execute Command Buffer button.
The second option, Save Command File..., saves the contents of the command buffer into a file.
The third option is Log Script and Results..., which opens a file save dialog box. The user can choose a
location for a log file to be written using the file save dialog. When the Execute Command Buffer button is
pressed, the script will run and the script, along with resulting data read back during the script, will be
saved to the file specified. The log file is a standard text file which can be opened with any text editor, and
looks much like the source script file, but with the additional information of the result of each script
command executed.
The third menu item is a submenu of Recently Opened Files. This list is simply a list of script files that

The Options menu (Figure 15) provides two settings suitable for command line interface users and for
troubleshooting. These settings allows the user to evaluate the device in its most basic form.
The first option, Hardware Reset on Startup, enables (checked) and disables (unchecked) the hardware
reset commands every time the GUI starts. If checked, a series of commands will be sent to the TAS1020
to hardware reset the TLV320AIC12K/14K at startup. If unchecked, nothing will be written to the
TLV320AIC12K/14K when the GUI starts. This option is useful if the user wants to keep the registers
intact when closing and re-opening the GUI. Keep in mind that, every time the EVM-K is connected or
reconnected, a hardware reset must be done in order to write to the codec either by pushing the Hardware
Reset button on the GUI, pressing the push-button on the EVM or by using the command line interface.
The second option, Hardware Reset on USB reconnection, enables (checked) and disables (unchecked)
the hardware reset commands every time the EVM-K is reconnected while using the GUI. If unchecked, a
manual hardware reset must be done if writing to the codec as stated on the paragraph above.

The actual USB protocol used as well as instructions on writing scripts are detailed in the following
subsections. While it is not necessary to understand or use either the protocol or the scripts directly,
understanding them may be helpful to some users.
6.9.1
USB-MODEVM Protocol
The USB-MODEVM is defined to be a Vendor-Specific class, and is identified on the PC system as an
NI-VISA device. Because the TAS1020 has several routines in its ROM which are designed for use with
HID-class devices, HID-like structures are used, even though the USB-MODEVM is not an HID-class
device. Data passes from the PC to the TAS1020 using the control endpoint.
Data is sent in an HIDSETREPORT (see Table 7):

Writing Scripts
A script is simply a text file that contains data to send to the serial control buses. The scripting language is
quite simple, as is the parser for the language. Therefore, the program is not very forgiving about mistakes
made in the source script file, but the formatting of the file is simple. Consequently, mistakes should be
rare.
Each line in a script file is one command. There is no provision for extending lines beyond one line. A line
is terminated by a carriage return.
The first character of a line is the command. Commands are:
i=======
Set interface bus to use
r=======
Read from the serial control bus
w = = = = = = = Write to the serial control bus
#=======
Comment
b=======
Break
d=======
Delay
The first command, i, sets the interface to use for the commands to follow. This command must be
followed by one of the following parameters:
i2cstd
Standard mode I2C Bus
i2cfast
Fast mode I2C bus
spi8
SPI bus with 8-bit register addressing
spi16
SPI bus with 16-bit register addressing
gpio
Use the USB-MODEVM GPIO capability
For example, if a fast mode I2C bus is to be used, the script would begin with:
i i2cfast
No data follows the break command. Anything following a comment command is ignored by the parser,
provided that it is on the same line. The delay command allows the user to specify a time, in milliseconds,
that the script will pause before proceeding.
Note:
UNLIKE ALL OTHER NUMBERS USED IN THE SCRIPT COMMANDS, THE DELAY TIME
IS ENTERED IN A DECIMAL FORMAT. Also, note that because of latency in the USB bus
as well as the time it takes the processor on the USB-MODEVM to handle requests, the
delay time may not be precise.
A series of byte values follows either a read or write command. Each byte value is expressed in
hexadecimal, and each byte must be separated by a space. Commands are interpreted and sent to the
TAS1020 by the program using the protocol described in Section 6.9.1.
The first byte following a read or write command is the I2C slave address of the device (if I2C is used) or
the first data byte to write (if SPI is used—note that SPI interfaces are not standardized on protocols, so
the meaning of this byte will vary with the device being addressed on the SPI bus). The second byte is the
starting register address that data will be written to (again, with I2C; SPI varies—see Section 6.9.1 for
additional information about what variations may be necessary for a particular SPI mode). Following these
two bytes are data, if writing; if reading, the third byte value is the number of bytes to read, (expressed in
hexadecimal).

For example, to write the values 0x45 0xA0 to an I C device with a slave address of 0x80, starting at a
register address of 0x01, one would write:
#example script
i i2cfast
w 80 01 45 A0
r 80 01 02
This script begins with a comment, specifies that a fast I2C bus will be used, then writes 0x45 0xA0 to the
I2C slave device at address 0x80, writing the values into registers 0x01 and 0x02. The script then reads
back two bytes from the same device starting at register address 0x01. Note that the slave device value
does not change. It is not necessary to set the R/W bit for I2C devices in the script; the read or write
commands will do that for the user.
Any text editor may be used to write these scripts; Jedit is an editor that is highly recommended for
general usage. For more information, go to: http://www.jedit.org.
Once the script is written, it can be used in the command window by running the program, and then
selecting Open Command File... from the File menu. Locate the script and open it. The script will then be
displayed in the command buffer. The user may also edit the script once it is in the buffer and save it as
specified in Section 6.9.
Once the script is in the command buffer, it may be executed by pressing the Execute Command Buffer
button. If the user has placed breakpoints in the script, it will execute to that point, and a dialog box will
show up with a continue button to continue executing the script.
Please refer to sections 3.1 (Power Down and Reset) and section 3.2 (AIC12 Control Register
Programming Procedures) on the TLV320AIC12/13/14/15 Codec Operating In Stand-Alone Slave Mode
application note for important details on programming the codec.
Special care must be taken when writing subregisters (4A-4B and 5A-5D).
Example: w 80 01 45 A0 01 20 B8 00
The previous command writes registers 1, 2, 3, 4A, 5C and 6. It will not increment from 3 to 4A and
then to 4B. The subregister to be written will depend on the data.

arising from the handling or use of the goods. Due to the open construction of the product, it is the user’s responsibility to take any and all
appropriate precautions with regard to electrostatic discharge.
EXCEPT TO THE EXTENT OF THE INDEMNITY SET FORTH ABOVE, NEITHER PARTY SHALL BE LIABLE TO THE OTHER FOR ANY
INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES.
TI currently deals with a variety of customers for products, and therefore our arrangement with the user is not exclusive.
TI assumes no liability for applications assistance, customer product design, software performance, or infringement of patents or
services described herein.
Please read the User’s Guide and, specifically, the Warnings and Restrictions notice in the User’s Guide prior to handling the product. This
notice contains important safety information about temperatures and voltages. For additional information on TI’s environmental and/or

No license is granted under any patent right or other intellectual property right of TI covering or relating to any machine, process, or
combination in which such TI products or services might be or are used.
EVM WARNINGS AND RESTRICTIONS
It is important to operate the EVM daughterboard within the input voltage range of 3.3 V to 5 V and the output voltage range of 0 V to 5 V
and the EVM motherboard within the input voltage range of 6 VDC to 10 VDC when using an external AC/DC power supply. Refer to the
USB-MODEVM Interface Power section of this manual when using lab power supplies.
Exceeding the specified input range may cause unexpected operation and/or irreversible damage to the EVM. If there are questions
concerning the input range, please contact a TI field representative prior to connecting the input power.
Applying loads outside of the specified output range may result in unintended operation and/or possible permanent damage to the EVM.
Please consult the EVM User's Guide prior to connecting any load to the EVM output. If there is uncertainty as to the load specification,
please contact a TI field representative.
During normal operation, some circuit components may have case temperatures greater than 30°C. The EVM is designed to operate
properly with certain components above 85°C as long as the input and output ranges are maintained. These components include but are
not limited to linear regulators, switching transistors, pass transistors, and current sense resistors. These types of devices can be identified
using the EVM schematic located in the EVM User's Guide. When placing measurement probes near these devices during operation,
please be aware that these devices may be very warm to the touch.
