When Using Pattern B as a Trigger Condition
12.
Use jog shuttle & SELECT to set the pattern MOSI (CH2) or MISO (CH3) to be
assigned to Pattern B.
13.
Use jog shuttle & SELECT to set the data length of the determination pattern to
be specified from 1 to 8 bytes (Data Byte box). The number of bytes displayed
in the B Pattern box is set to the number of bytes that matches the selected
result.
14.
Use jog shuttle & SELECT to set the determination pattern for each byte in
hexadecimal or binary (B Pattern box). When determination is not to be
performed, select X.
15.
Use jog shuttle & SELECT to set the condition of Pattern B to True or False
(Condition box).
16.
Use jog shuttle & SELECT to select whether to compare the Pattern B to the
pattern immediately after the byte count (First Byte) or continue to compare until
SS is negated (Anywhere) (After Byte Count box).
Select the data length
of Pattern B in the
range of 1 to 8 bytes.
Set the Pattern B condition to
True or False.
Select this when using
pattern B as a trigger
condition.
Set the data assigned to
Pattern B to MOSI (CH2) or
MISO (CH3).
Set the determination pattern
per byte using hexadecimal
or binary values.
Select whether to compare Pattern B to the pattern immediately
after the byte count (First Byte) or continue to compare until SS
is negated (Anywhere).
17.
Press ESC. The SPI Setup dialog box closes.
Setting the Assignment Conditions of the SPI Bus Signal
18.
Press the Set Pattern soft key. The Set Pattern dialog box displays the
assignment conditions of the SPI Bus signals of CH1 to CH4.
19.
Use jog shuttle & SELECT to set the slope of the CH1 (SCK) edge to (rising
edge) or (falling edge).
20.
Use jog shuttle & SELECT to set the CH4 (SS) enble state to H (high) or L
(low).
Set the CH1 (SCK) edge slope
to or .
Set the CH4 (SS) enable state
to H or L.
21.
Press the ESC. The Set Pattern dialog box closes.
