scan input
Notes
1. I = input, O = output, P = power, NC = not connected, st = strapping, pu = pull-up, pd = pull-down, od
= open-drain.
2. In accordance with the “IEEE1149.1” standard the pads TDI, TMS, TCK and TRST are input pads
with an internal pull-up transistor and TDO is a 3-state output pad.
3. For board design without boundary scan implementation connect the TRST pin to ground.
4. This pin provides easy initialization of the Boundary Scan Test (BST) circuit. TRST can be used to
force the Test Access Port (TAP) controller to the TEST_LOGIC_RESET state (normal operation) at
once.
5. Pin strapping is done by connecting the pin to the supply via a 3.3
κΩ
resistor. During the power-up
reset sequence the corresponding pins are switched to input mode to read the strapping level. For the
default setting no strapping
