1.6 Emulation

1.6.1 Temporary Breakpoints

• Run... (Run menu)

Do not set temporary breakpoints to an area wherein PC Break (User Read-only) cannot be set. Otherwise,

user program execution will not stop at the breakpoint. Moreover, the On Chip Breakpoint may remain. In

this case, delete the breakpoint from the [Breakpoints] window.

1.6.2 Rate of Stepping

To perform stepping continuously with the [Image View] window or [Waveform] window open, select the

rate of stepping either from 0 to 5.

1.6.3 Go to Cursor

The [Go to Cursor] function uses one PC breakpoint. Note the followings:

• To use the [Go to Cursor] function, the number of PC breakpoints must be 255 or less.

• To use the [Go to Cursor] function for the ROM area on the target system, do not use the On Chip

Breakpoint by the PC break.

1.6.4 Note on Occurrence of Breaks

When a break occurs during execution of the user program with a dialog box open, the state of HEW2

may not transit to the breaking state. In this case, close the dialog box and select [Halt Program] from the

[Debug] menu or press the [Halt Program] button on the toolbar. You can check whether a break has

occurred or not by the RUN lamp (LED) on the emulator station. The RUN lamp (LED) is illuminated

while the user program is running.

1.6.5 Execution Status Display

• Execution Status Display on Status Bar

At memory access wait, not the address where the access is halted, but the next fetched address is

displayed.

1.6.6 Source-Level Execution

• Step

Even standard C libraries are executed. To return to a higher-level function, enter Step Out. In a for

statement or a while statement, executing a single step does not move execution to the next line. To move

to the next line, execute two steps.

1.7 The Load/Save of the Session File

Load the file after you confirm that the H/W environment is the same as that when the last session file was

loaded.

Note that the operation of HEW may become incorrect when Target Clock is chosen at the time when the

session file was saved and the target clock was not supplied at the time when the session file was loaded.

1.8 Assembling and Disassembling

1.8.1 [Disassembly] Window

When the [Disassembly] window is first opened after installation of the HEW2, changing the size of the

window may not be available. In this case, close the [Disassembly] window and then open it again.
