    Writes or reads the elements of a digital table.


    digital table in

    Input value of the digital table.


    digital table out

    The resulting digital table.



    A 2D array that contains the data values as 8-bit unsigned integers. Each row in the 2D array represents a single binary value for one sample of data with the most significant bit of data in the first column and the least significant bit of data in the last column. Each value in the 2D array corresponds to a digital value, or digital data state, represented in output digital table. The following table shows the digital data state represented by each of the valid 8-bit unsigned integers.

    Value Digital Data State Description
    0 0 (Drive Low) Force logic low. Drive to the low voltage level (VOL).
    1 1 (Drive High) Force logic high. Drive to the high voltage level (VOH).
    2 Z (Force Off) Force logic high impedance. Turn the driver off.
    3 L (Compare Low) Compare logic low (edge). Compare for a voltage level lower than the low voltage threshold.
    4 H (Compare High) Compare logic high (edge). Compare for a voltage level higher than the high voltage threshold.
    5 X (Compare Unknown) Compare logic unknown. Do not compare.
    6 T (Compare Off) Compare logic high impedance (edge). Compare for a voltage between the low voltage threshold and the high voltage threshold.
    7 V (Compare Valid) Compare logic valid level (edge). Compare for a voltage level either lower than the low voltage threshold or higher than the high voltage threshold.


    An array that defines non-incremental transitions to compress the digital data. The transitions array must contain the same number of rows as the data array. If this is an empty array, data is uncompressed data.
