Sequential Break Extension Setting:
(a) Indicates the channel name for setting conditions.
(b) Selects a condition that is satisfied before the channel which sets up conditions.
When a channel name is selected, it is required that the condition of the channel selected here
must have already been satisfied.
When [CPU Match flag] is selected, the CPU match flag must be set.
When a condition is selected by the channel selected here, no break will occur.
(c) After conditions have been matched, the CPU match flag is set or cleared.
When a program breaks, the CPU match flag is initialized.
Set the event condition for each channel in the [Event Condition] dialog box; this also applies to
the [SystemBus Sequential Extend] page.
