This user's guide describes the characteristics, operation, and use of the TLV320AIC3007EVM-K. This
evaluation module (EVM) allows the user to evaluate the TLV320AIC3007 audio codec. The
TLV320AIC3007 is a complete 2-channel audio codec with an integrated Class-D speaker amplifier. It also
has many inputs and outputs, extensive audio routing, mixing, and effects capabilities. A complete circuit
description, schematic diagram, and bill of materials are included. Note that the TLV320AIC3007 only
2
uses the I
C™ bus for register control. Any references to the SPI control bus in this document is due to
the presence of this interface on the USB-MODEVM motherboard.

GPIO Capability www.ti.com GPIO Capability The USB-MODEVM has seven GPIO lines. Access them by specifying the interface to be 0x08, and then using the standard format for packets—but addresses are unnecessary. The GPIO lines are mapped into one byte (see Table G-3): Table G-3. - Page 49 Writing Scripts www.ti.com Writing Scripts A script is simply a text file that contains data to send to the serial control buses. The scripting language is simple, as is the parser for the language. Therefore, although the program is not forgiving about mistakes made in the source script file, the formatting of the file is simple.
- Page 50 Writing Scripts www.ti.com This script begins with a comment, specifies that a fast I C bus is used, then writes 0xAA 0x55 to the I slave device at address 0x90, writing the values into registers 0x03 and 0x04. The script then reads back two bytes from the same device starting at register address 0x03.
