Communication Settings - These settings determine how the data of the selected channels
Enable Signal Channels - This item is selected (checked) by default. Uncheck this item to
Invert CLK/Data - These items are de-selected (unchecked) by default. Check these items to
Channel Selection - This is where you will associate a signal definition with the physical
modes, an example of each mode is displayed in the current color scheme, followed by a
listing of any items that allow custom colors (i.e. Signal Color, Signal Background). Click on
an item in the list to select a new color.
will be be decoded. To change these items, use the appropriate property editors below.
Each signal definition has its own decoder, so these settings will not affect other
Synchronous signal definitions.
Data Bits - Select the number of DATA bits in the packet. Options are from 1 to 32 bits.
Enable State - Choose the logic level of the Enable channel that determines when the clock
channel is "valid". Options are LOW, HIGH, IGNORE. Whenever the Enable channel
matches the indicated state, the clock and data channel will be decoded. Set this option to
"Ignore" if these channels are always valid and you do not wish to use the Enable channel as
a qualifier.
Clock Edge - Choose the transition state of the Clock channel that determines when the
data channel is "valid". Options are FALLING, RISING, BOTH. Whenever the Clock channel
transition matches the selection, the data channel will be decoded. Set this option to "Both"
to decode the data on every transition of the Clock channel.
Sync Start of Packet - Use this button to synchronize to the beginning of the first packet in
the captured data. Normally this is unnecessary unless you have set the Enable qualifier to
"Ignore". Unlike Asynchronous signals, Synchronous signals do not have a specific bit rate,
so DigiView will not automatically find the beginning of a packet when the qualifier is not
used. Right-Click on the button to advance the decoder by one bit and Left-Click to backup
by one bit. Click multiple times or hold the button down to repeat the action. The decoders
"shift-bit" action is performed in a circular fashion and is limited to the number of bits
required for a single packet. The numerical display to the right of the button tracks the bit
position from the beginning of the available data.
completely disable the Signal Definition. It is recommended to disable any signals that use
channels that are not connected to a physical device. When a capture takes place ("Run"),
any channels that are assigned to disabled signals will be ignored instead of using valuable
capture space.
have the value of the associated channel "inverted" before being decoded. This setting will
not affect any other signal definitions that may use the same channels.
channels or connections to the outside world. Each signal definition type will have one or
more channel selection groups and will allow one or more channels to be selected for each
group. Each channel selection group will be identified on its left if more than one group is
available for the signal type.
To select a channel, click on the " - " below the proper color (and channel number) that
corresponds to the physical connection of the DigiView Cable (see:
Lines). Channels that are selected for this signal will replace the " - " with a blue "dot" as
shown above. Channels that are already defined in other signal definitions will have a darker
color around the selection area for the channel (as channels 0 through 6 do in the graphic
above).
