SPI Decoding (Option)
SPI bus is based on the master-slave configuration and usually consists of chip select
line (CS), clock line (SCLK), and data line (SDA). Wherein, the data lines include the
master input/slave output (MISO) data line and master output/slave input (MOSI)
data line. The oscilloscope samples the channel data on the rising or falling edge of
the clock signal (if the source is an analog channel, the oscilloscope will also judge
each data point (logic "1" or logic "0") according to the preset threshold level).
