because there are no internal pull-ups to guarantee their state
during prolonged three-state conditions resulting from typical
EZ-ICE debugging sessions. These resistors may be removed
when the EZ-ICE is not being used.
Target System Interface Signals
When the EZ-ICE board is installed, the performance on some
system signals changes. Design the system to be compatible with
the following system interface signal changes introduced by the
EZ-ICE board:

asserted by the EZ-ICE board’s DSP.
