low for at least 250 nanoseconds in order to reset the
TL3M device’s Test Access Port (TAP) controller. The
TAP controller may also be reset by holding the TMS sig-
nal lead high for at least five clock cycles of TCK. In appli-
cations which will not be using the boundary scan
feature, this lead must be tied low, thereby holding the
TAP controller reset.
