Test Data Output: Boundary scan output for data
and test instructions from internal test registers.
Test Mode Reset: A 1 microsecond (minimum) low
on this lead resets the boundary scan;
recommended for use after power-up initialization as
well. This lead should be held low whenever
boundary scan operations are not being performed.
Test Mode Select: Boundary scan test mode select.
This signal must be pulled high. 4.7k
recommended.
Test Data Input: Boundary scan input for data and
test instructions. 4.7k
Test Clock: Boundary scan clock. Input signals are
clocked in on its rising edge.
Hardware Reset: An active low pulse with minimum
width of 1 ms which must be applied after power is
applied to reset all registers, counters, and FIFOs.
The reset is asynchronous going into the reset state,
but requires all external clocks to be active and
stable during the reset state.
Test Mode: For TranSwitch testing purposes only.
