21.BREAKPOINT
Session file
When the BREAKPOINT address set in the session file is H'0, the breakpoint will not be
set. If the address set as the breakpoint is wrong, the error message is not output. The
breakpoint is registered as DISABLE in the [Breakpoints] window.
Breakpoint cancellation
When the contents of the BREAKPOINT address is modified during user program
execution, the following message is displayed when the user program stops.
BREAKPOINT IS DELETED A=xxxxxxxx
If the above message is displayed, cancel all BREAKPOINT settings with the [Delete All]
or [Disable] button in the [Breakpoints] window.
[Run program] dialog box
If a disabled BREAKPOINT address is specified as a stop address in the [Run Program]
dialog box, the disabled BREAKPOINT will become enabled after the user program has
stopped.
[Breakpoints] window
During user program execution, it is impossible to jump from the breakpoint to the source
or address line on the [Source] or [Disassembly] window by using [Go to Source] in the
popup menu displayed on the [Breakpoints] window.
22.Number of BREAKPOINT and [Stop At] Settings in the [Run...] Menu
The maximum number of BREAKPOINTs and [Stop At] settings allowed in the [Run...] menu
is 255. Therefore, when 255 BREAKPOINTs are set, specification by [Stop At] in the [Run...]
menu becomes invalid. Use the BREAKPOINTs and [Stop At] in the [Run...] menu with 255
or less total settings.
23.Note on RUN-TIME Display
The execution time of the user program displayed in the [Status] window may not be accurate
since the timer in the host computer is used.
24.Note on Displaying COMMUNICATION TIMEOUT ERROR
If COMMUNICATION TIMEOUT ERROR is displayed, the emulator cannot communicate
with the chip. Select [Initialize] from the [File] menu to initialize the emulator.
25.Note on Downloading Program
In the [Load Program] dialog box, which is opened when [Load Program…] is selected, the
verify function is invalid. After downloading the program, perform verify in the [Verify S-
Record File with Memory] dialog box, which is opened when [Verify] is selected from the
[Memory] menu.
