Protocol Decoding
You can use the protocol analysis to discover errors, debug hardware, and accelerate
development easily, ensuring you to accomplish the projects with high speed and
good quality. Protocol decoding is the basis of protocol analysis. Only protocol
analyses with correct protocol decoding are acceptable, and only correct protocol
decoding can identify more error information. This oscilloscope provides four bus
decoding modules (Decode 1, Decode 2, Decode 3, and Decode 4) to make common
protocol decoding for the input signals of the analog channels. It provides standard
serial decodes including Parallel, RS232/UART, I2C, CAN, and SPI; optional serial
decodes including LIN, CAN-FD, FlexRay, I2S and MIL-STD-1553. As the decoding
functions and setting methods of Decode1, Decode2, Decode3, and Decode4, this
chapter takes Decode1 as an example for illustration.

19.1 Parallel Decoding
Parallel bus consists of clock line and data line. As shown in the figure below, CLK is
the clock line, Bit0 and Bit1 are the 0 bit and 1st bit on the data line. 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.
