Format of breakpoints list box
The Breakpoints list box contains all the breakpoints that have been added,
including effective breakpoints and non-effective breakpoints. The Add
button should be used to add new breakpoints to the list box, and the Delete
button to remove breakpoints from the list box. The format of each break-
point in the list box is as follows:
<status> {<space and read/write>, <location>,
<data content>, <external signal>}
where <status> is effective status. ’+’ is effective (enabled) and ’-’ is non-ef-
fective(disabled). <space and read/write> is the space type and operating
mode. ’C’ is the code space, ’D/R’ is the data space with read, ’D/W’ is the
data space with write, ’D/RW’ is the data space with read and write.
<location>, <data content> and <external signal> have the same data
format as the input form respectively.
How to set breakpoints
There are two methods to set/enable a breakpoint, one is by using the
Breakpoint command from the Debug menu, the other is by using the
Toggle Breakpoint button on the toolbar. The rules of the breakpoint
mechanism are as follows:
•
If the breakpoint to be set is not in the breakpoint list box (Fig 5-3), then
the descriptive items must be designated first, then added to the break-
point list box.
•
As long as the breakpoint exists in the list box, it can be made effective
by Enabling the breakpoint if it fails to be initially effective.
•
Press the OK button for confirmation. Otherwise, all changes here will
not be effective.
•
When using the Toggle Breakpoint button on the toolbar, the cursor
should first be moved to the breakpoint line, and then the Toggle Break-
point button pressed. If an effective breakpoint is to be changed to a
non-effective breakpoint, this can be achieved by merely pressing the
Toggle breakpoint button.
