Kit Operation

Figure 14. File Menu

The Options menu (

) 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.

Figure 15. Options Menu

Under the Help menu is an

About...

menu item (

) which displays information about the

TLV320AIC12KEVM/14KEVM software.
