When a logic low, this signal asynchronously resets the
boundary scan test circuitry and puts the test controller into
the reset state. This state allows normal system operation. Tie
to ground when boundary scan is not implemented. This PAD
has an internal pullup resister to VDD.
Generated externally by the system board or by the tester. Tie
to ground when boundary scan is not implemented.
Decoded to control test operations. This PAD has an internal
pullup resister to VDD.
Outputs serial test pattern data.
Input for serial test pattern data. This PAD has an internal
pullup resister to VDD.

12 mA drive. Direct Buffer of HRST* input.
Forty-nine balls are provided for supply voltage.
Eighty-five balls are provided for ground. (The 36 balls in the
center help in heat dissipation.)
Provides Electrostatic Discharge (ESD) protection and over
voltage protection. When the device is used with 5 V devices
on the board, tie this pin to 5 V for 5 V signal tolerance.
Otherwise, tie to 3.3 V.
NOTE:
