##### Synopsis

    TargetInterface.setMaximumJTAGFrequency(hz)

##### Description

TargetInterface.setMaximumJTAGFrequency allows the maximum TCK frequency of the currently connected JTAG interface to be set dynamically. The speed setting will only apply for the current connection session, if you reconnect the setting will revert to the speed specfied by the target interface properties. Calls to this function will be ignored if adaptive clocking is being used.
