Hi,

There is "TEST" pin in PCM1754-Q1. But there is no description about detail of this function.

Could you please tell me funcion detail of "TEST" pin ?

Best Regards,

    The "test" pin is used by TI during characterization and final test. Including a test pin on a part like this saves us valuable development time since we can use it to access internal signals (this makes debugging the device during the development stage much easier). During final ATE testing, it lets us test things that would be difficult otherwise.

    This pin should not be used by you and can be left open or grounded.

    Thanks,
