(6) Saving memory data
(7) Comparing memory contents and object files
The content of a specified area can be saved to a file in binary, text (hexadecimal dump format), or
Motorola S3 format. (df command)
Memory contents are compared with a specified object file in srf33 format. (mc command)
Updating of the [Memory] window
When you open the [Memory] window using the [Memory] command on the [Window] menu, the contents
of the memory are displayed in the window. The data at all addresses can be checked by scrolling the
window. You can use the d* (db, dh, dw) command or a dialog box that appears by double-clicking on the
window to specify an address so the window starts displaying the memory contents beginning with the
specified address.
When the [Memory] window is open you may modify the address displayed in the window, but the display
contents of the [Memory] window will not be updated by that modification. To update the display contents,
you need to execute the d* command or click on the [Memory] window.
The [Memory] window is cleared by reading a file. In such a case, redisplay the window using the method
described above.
When the program is executed successively, the [Memory] window will be updated immediately after a
break occurs. During step execution, the [Memory] window is updated every step. This automatic update
function can be disabled using the md command.
Updating the [Source] window
When the [Source] window is open you may modify the content of an address displayed in the window, but
the display contents of the [Source] window is not updated by that modification. To update the display
contents, you need to temporarily switch the display mode of the [Source] window using a command or
scroll the [Source] window in the vertical direction. Note that when code is modified, the disassemble result
changes, but the display contents of source do not change.
• The S5U1C33000H reads memory data 8 bytes at a time. Therefore, data may be read

exceeding the range specified using a command (to maximum 7 bytes ahead). Pay attention
when reading the I/O memory since some registers change their status by reading.
S5U1C33000H or S5U1C330M2S, byte-access commands (eb, fb, mv) cannot be used. Be
sure to use a half-word- or word-access command (eh, ew, fh, fw, mvh, mvw). The file load
commands (lf, lh) always write data in half-word units.
