3.1. Turn ON/OFF Auto-Adjust Feature

JTAG config command

The JTAG config command can be used to query the JTAG frequency auto-adjust status and turning ON/OFF the feature.

To turn off the JTAG frequency auto-adjust feature, use the following command: 
jtagconfig --setparam <cable number> JtagClockAutoAdjust 0
To turn on the JTAG frequency auto-adjust feature, use the following command: 
jtagconfig --setparam <cable number> JtagClockAutoAdjust 1
You may use the following command to check if auto-adjust feature is enabled. The expected output is "0" if auto-adjust is disabled and "1" if the auto-adjust is enabled 
Jtagconfig --getparam <cable number> JtagClockAutoAdjust

Programmer GUI

A checkbox is added in the Programmer's "Hardware Setup" dialog box to turn On/Off the frequency adjust feature. The checkbox is enabled when the frequency auto-adjust feature is available . Otherwise, it is greyed out. If the frequency auto-adjust-feature is enabled, new adjusted TCK frequency value will be shown under the message box of the programmer GUI.
