SPI serial bus menu fields and controls.
Field or control Description
Display Turns on or off displaying the bus on the Waveform view.
Label Enter a label for the bus. The default label is the selected bus type.
To enter label text, double-tap the field and enter label using the virtual keyboard, or tap the
field and enter text from an attached keyboard.
Position Sets the vertical position of the bus waveform. The default position is vertically centered in a
slice (in Stacked mode), or center screen in Overlay mode. The unit of position is screen
divisions.
Set to 0 Sets the vertical position to 0 divisions (centered vertically in a slice or on the screen.
Bus Type Set to SPI.
Framing Set to Slave Select (SS) or Idle framing modes.
SCLK Input Select the channel source and threshold level for the Serial Clock signal (output from master).
Set the Polarity to rising or falling edge of the clock signal used by the master device to start
transferring bits.
SS Input Select the channel source and threshold level for the Slave Select signal to start
communications with the slave device.
Set the Polarity to use Active High or Active Low logic for the SS signal.
Available when Framing = SS.
SDA Input Select the channel source and threshold level for the Serial Data signal (bidirectional).
Set the Polarity to use Active High or Active Low logic for the SDA signal.
Word Size Enter the word size, in bits. Common word sizes are 8, 16, and 32.
Bit Order Set to most significant bit first (MS) or least significant bit first (LS).
Idle Time (Framing = ) Set the idle frame time.
Available when Framing = Idle.
Display Format Sets the waveform view to show just the decoded bus information, or the decoded bus plus the
source signal waveforms.
Decode Format Sets the decode format used to display the bus information. Formats are Hex and Binary.
