JTAG Frequency Selection
The tests listed in the Status box are run when you click Test in the JTAG
Frequency Selection dialog box. The blue arrow points to the current fre-
quency. The arrow does not change after you run the tests because Cancel
goes back to using the frequency pointed to by the blue arrow. To use
a different frequency, select the appropriate frequency from the list and
click Test. Click OK to use the frequency that is highlighted and tested
already.
Table 1-1 describes the JTAG Frequency Selection dialog box.

Updates status of the tests indicated within the test group. The test
status indicator can show a “running” icon, “not running” icon, “pass”
icon, or “fail” icon, depending on the test status.
Test
Tests the selected frequency by running the tests in the Status group.
NOTE: If tests fail, you may have to shut down the IDE and restart
your session.
OK
Saves the selected frequency. This should only be highlighted if all the
tests have passed.
Cancel
Continues using the frequency pointed to by the blue arrow.
 If you encounter a problem launching the CCES or VisualDSP++
at a certain frequency, delete your debug configuration/session and
create a new debug configuration/session. This sets TCK back to
the default value.
