Signal Description and Termination
Note:
Some target
boards may require a
pull-down resistor on
the TRST* signal to
assure normal device
operations when not
in boundary-scan test
mode
Note:
The target
TDI signal is driven
by the TDO signal of
the
boundary-scan
controller
Note:
The target
TDO signal drives
the boundary scan
controller’s
TDI
signal
