Parallel Decoding
Parallel bus consists of clock line and data line. As shown in the figure below, CLK is
the clock line, while Bit0 and Bit1 are the 0 bit and 1st bit on the data line respectively.
The oscilloscope will sample the channel data on the rising edge, falling edge or the
rising/falling edge of the clock and judge each data point (logic "1" or logic "0")
according to the preset threshold level.
