The CBT device could be used to limit the number of devices that the driving
EMU0-EMU1 signal is loaded with; thereby limiting the amount of capacitance loading
that is seen by the driving EMU0-EMU1 signal.
Using this solution would require the user to have a manual jumper selection to enable
which bank of devices that emulator would able to establish HSRTDX communication
with.
Figure 3-9 shows a possible solution to minimize the loading effects of having too many
target devices connected on the EMU0/EMU1 signals.
Please refer to Section 3.5 for recommended connections of the JTAG signals.
