DLPC3478: TRIG_IN

Petr Zkrat

Part Number: DLPC3478

Hi,

in DLPC3478 in datasheet there is a following statement regarding 3DR pin:

"3DR.....For light control applications: Reserved for TRIG_IN (Input). Applicable in Internal Pattern Streaming Mode only"

However on "Figure 33 Internal Pattern Streaming Mode" (page 52) GPIO_5 is used as a TRIG_IN. 

Is this just a datasheet issue or is there any meaning behind it?

Thanks

Petr

    Hi Petr,

    I believe the reference to the GPIO is in error, but I will check to confirm.

    Thanks,

    Hi Petr,

    As Kyle mentioned "the reference to the GPIO is in error" is correct. 

    So i am repeating the same line as mentioned in Datasheet and you also mentioned in your query 

    "3DR.....For light control applications: Reserved for TRIG_IN (Input). Applicable in Internal Pattern Streaming Mode only"

    We will correct the Figure 33 in our next datasheet update. Thanks for pointing out the issue.

    Thanks,

    Navneet
