TMS320F28069: about TEST2 pin of F28069

Part Number: TMS320F28069
Other Parts Discussed in Thread: TEST2

Hi all,

Although it is described in DS(SPRS698F) that TEST2 pin has to be open,
is there a possibility that the device malfunctions due to noise entering this pin?
I want to know whether noise suppression is necessary for this terminal.

Best regards,
Sasaki

Shigetsuna-san,

TEST2 is a test pin connected to some internal circuitry that is activated in certain test-modes. These test-modes should not occur during normal application runtime, during which the pin should remain high impedance. Noise should have little effect on this pin. However, it may be grounded via a 10K resistor.
