Setting the JTAG Clock Speed (communications
speed)
The HP processor probe needs to be configured to communicate at a rate
which is compatible with your target processor. The JTAG Clock speed is
independent of processor clock speed. In general, speed=1 can always be
used and provides the best performance. With some target systems that have
additional loads on the JTAG lines or with target systems that do not quite
meet the requirements described in chapter 4, setting speed to a slower
setting may enable the probe to work.
