When SPI -> Pattern Is Selected
20.
Press the Set Pattern soft key. The Set Pattern dialog box displays the
assignment conditions of the SPI Bus signals of CH1 to CH4 and the pattern
setup screen of CH5 to CH8.
21.
Use jog shuttle & SELECT to set the slope of the CH1 (SCK) edge to (rising
edge) or (falling edge).
22.
Use jog shuttle & SELECT to set the CH4 (SS) enable state to H (high) or L
(low).
23.
Use job shuttle & SELECT to set the clock channel to None or any channel
from CH5 or CH8 (Clock CH box).
24.
Use jog shuttle & SELECT to set the patterns of CH5 to CH8 using H (high), L
(low), and X. For the channel set as the clock channel in step 23, set the slope
to (rising edge) or (falling edge).
25.
If you set the clock channel to None in step 23, use jog shuttle & SELECT to
set the pattern condition to True or False (Condition box).
Set the CH1 (SCK) edge slope
to or .
Set the CH4 (SS) enable state
to H or L.
Select the CH5 to CH8
pattern using H, L, and X.
Set the pattern condition to
Enter or Exit.
Select the clock channel from
CH5 to CH8.
When Clock CH is set to None
When Clock CH is set to any channel
from CH5 to CH8
* Set the slope of the channel selected for the clock channel to or .
26.
Press ESC. The Set Pattern dialog box closes.
Proceed to step 27.
Note
If you set Combination to SPI -> Pattern and set the patterns of CH5 to CH8 to all Xs, triggers
will not be activated. If the clock channel is set to any of the channels from CH5 to CH8, the
pattern conditions of other channels are always set to true.
