The ICE fuse cut immediately after
activation.
<ILLEGAL VERSION ICE6200>
appears on the screen immediately after
activation.
<ILLEGAL VERSION PARAMETER
FILE> appears on the screen immedi-
ately after activation.
Immediate values A (10) and B (11)
cannot be entered correctly with the A
command.
<UNUSED AREA> is displayed by the
SD command.
You can not do a real-time run in
break-trace mode.
Output from the evaluation board is
impossible when data is written to the I/
O memory for Buzzer and Fout output
with the ICE command.
An R error occurs although the address
is correctly set in the segment source
file.
Remedy measures
Check the following and remedy if necessary:
• Is the RS-232C cable connected correctly?
• Is the RS-232C driver installed?
• Is MODE.COM on the disk?
• Is the execution file correct?
PC-DOS ICS62XXW.EXE
• Is the DOS version correct?
PC-DOS Ver. 2.1 or later
• Is the DIP switches that set the baud rate of the main ICE
unit set correctly?
• Is the fuse of the ICE cut off?
Check the following and remedy if necessary:
• Are connectors F1 and F5 connected to the evaluation
board correctly?
• Is the target board power short-circuiting?
The wrong version of ICE is being used. Use the latest
version.
The wrong version of ICS62XXP.PAR is being used. Use
the latest version.
The A and B registers are reserved for the entry of A and B.
Write 0A and 0B when entering A (10) and B (11).
Example:
LD A, B Data in the B register is
loaded into the A register.
LD B, 0A Immediate value A is loaded
into the B register.
This massage is output when the address following one in
which data is written is unused. It does not indicates
problem. Data is correctly set in areas other than the read-
only area.
Since the CPU stops temporarily when breaking conditions
are met, executing in a real-time is not performed.
Output is possible only in the real-time run mode.
Check the following and remedy if necessary:
• Does the address symbol use capital letters?
• Are the output ports set for every two terminals?
