NOTE: TRST is an active high test pin and must be maintained low at all times during
normal device operation. An external pulldown resistor is required on this pin. The
value of this resistor should be based on drive strength of the debugger pods applicable to the design. A 2.2-kΩ resistor generally offers adequate protection. Since this is application-specific, it is recommended that each target board be validated for proper operation of the debugger and the application. (↓)
