High-Level TLK10232 Device Configuration
By default, the TLK10232 device and GUI are configured to run in Auto Negotiation 10G-KR mode. The
first window (
Figure 4
) has a selection box that allows easy configuration for all of the various operational
modes of the TLK10232 device. This is a hybrid control and will set all of the various control register bits
required for proper operation in that mode. Located to the right of this selection box is an LED indicator
panel displaying the value of the various controls bits set in that particular mode.
The default PRTAD[4:1] setting for TLK10232 EVM board and GUI is 4b’0000. If the PRTAD[4:1] value is
changed on the TLK10232 EVM board using the dip switch settings, the value must also be entered into
the GUI on the Front Panel above the Control pin settings. If there is a hardware/software mismatch, then
register read/write operations will fail. The same is true for the I
2
C Address on the TCA6424. Clicking the
0x22 allows the selection of address 0x23.
Figure 4. TLK10232 EVM GUI Operating Mode Configuration
When making changes to a particular control field in any of the high-level control windows, the value is
stored into the GUI’s register configuration array but is not immediately written to the device. When the
settings have changed and the settings of the GUI do not match the actual register settings of the EVM
device, the Require Update? light glows red, indicating that some setting has changed in the GUI
memory and needs to be sent to the device. When the device settings match the GUI’s memory the
Device Configured light glows green indicating that the board is configured as displayed in the GUI.
To change the various register settings in the GUI memory to a new value, simply find the particular
parameter field in the various windows, select the new value, and click the Save Settings button. The
change is discarded if the Save button is not clicked and the Current Value of the register is kept.
