SCANSTA112: TRANS Pin

frederic Fayolle

Part Number: SCANSTA112

Hello,


I have a board with a SCANSTA112 whose TRANS pin is tied to GND through 1KOhm resistor.

Can I validate this PIN temporarily(to entered into transparent mode) by the CONTROLSET register?
And if I do, is there a risk of damaging SCANSTA112?

Thank you in advance for your answer.

    Please refer to this app note: http://www.ti.com/lit/an/snla055h/snla055h.pdf.

    The control register may be modified in the same manner as the LSP select register by issuing the CONTROLSEL instruction. Some of the bits in the control register, such as the TRANS bit, assume default values on power up or reset according to the values on the SCANSTA112 input pins (see Table 4). Setting the TRANS bit in the control register to 1 when the SCANSTA112 is in stitcher normal mode will cause it to go to stitcher full transparent mode.

    Thanks
