Setting the Notation System of the Address Pattern or Data Pattern
6.
Use jog shuttle & SELECT to set the notation system used to set the pattern to
Hex or Bin (Pattern Format box). The format used to set the Address Pattern box,
Data1 Pattern box, and Data2 Pattern box are set to the specified notation system.
Selecting the Items Used as Trigger Conditions
7.
Use job shuttle & SELECT to select whether Start Condition, Address Pattern,
Data1 Pattern, Byte Count, and Data2 Pattern are used as trigger conditions. If
you select Address Patten, proceed to step 8. If you select Data1 Pattern,
proceed to step 9. If you wish to set Byte Count, proceed to step 11. If you
select Data2 Pattern, proceed to step 12.
•
Highlighting of the mark to the left of each item indicates that it is used as a trigger
condition.
•
Start Condition and Byte Count items are always used as trigger conditions (the mark
to the left is always highlighted).
•
If you do not wish to use byte count as a trigger condition, set Byte Count to 0 (see
step 11).
When Using Address Pattern as a Trigger Condition
8.
Use jog shuttle & SELECT to set the address pattern in hexadecimal or binary
(Address Pattern box). When determination is not to be performed, select X.
When using binary (BIN) notation, set the LSB using “R” (Read), “W” (Write), and “X.”
When Using Data1 Pattern as a Trigger Condition
9.
Use jog shuttle & SELECT to set the determination pattern of Data1 in
hexadecimal or binary (Data1 Pattern box). When determination is not to be
performed, select X.
10.
Use jog shuttle & SELECT to set the Condition of the Data1 Pattern to True or
False (Condition box).
When Setting the Byte Count
11.
Use jog shuttle & SELECT to set the byte count in the range of 0 to 9999 bytes
(Byte Count box).
•
If you do not wish to use byte count as a trigger condition, set the value to 0.
•
You can also set the byte count using the soft key that appears at the bottom of the
ENHANCED menu (a menu that appears when you carry out steps 1 to 3 on the
previous page). This byte count soft key menu appears only when I
