16. [I/O Registers] window
Display and modification
Do not change values in the [I/O Registers] window because the emulator uses the address
break controller.
Note that the E10A emulator does not support the display of the invalid module or bit
information in the [I/O Registers] window (described in section 8, Displaying Variables, in
the Hitachi Debugging Interface User's Manual).
Verify
In the [I/O Registers] window, the verify function of the input value is invalid.
17. Note on [Registers] Window Operation During Program Execution
Although a dialog box is displayed in which the register contents can be changed by double-
clicking the [Registers] window, do not change the register contents during program
execution.
18.
Note on Radix in the [Register] Dialog Box
The default input radix in the [Register] dialog box is hexadecimal irrespective of the Radix
display. When a radix other than a hexadecimal is input, specify the prefix code such as B'.
After the value has been input in the [Register] dialog box, the Radix setting is changed to
hexadecimal. When the radix other than a hexadecimal is used as a default, reset the Radix
display.
19. Software Break
Session file
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.
[Breakpoints] window
During user program execution, it is impossible to jump from the breakpoint to the source
or address line in the [Source] or [Disassembly] window by using [Go to Source] in the
popup menu displayed in the [Breakpoints] window.
When the software breakpoint is set in the flash memory area, the program is written to the
flash memory each time the user program is executed. At this time, note that the number
of rewritable times will be decreased.
Breakpoint cancellation
When the contents of the software 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 software breakpoint settings with the [Delete
All] or [Disable] button in the [Breakpoints] window.
