ROM sockets
• L.HEX, H.HEX
These are IC sockets for target program ROMs. Insert the ROM (L.HEX) containing the 8 low-order bits (I7 to
I0) of the machine code into the L.HEX socket, and the ROM (H.HEX) containing the 4 high-order bits (IB to
I8) into the H.HEX socket.
• F.HEX
This is the IC socket into which the ROM (F.HEX) is inserted. This ROM includes the function options
generated by the function option generator (FOG62N51, 6S3N7, 60N01, 60N02, 60N05) for the
S5U1C62N51E1.
• S.HEX
This is the IC socket into which the ROM (S.HEX) is inserted. This ROM includes the segment options
generated by the segment option generator (SOG62N51, 6S3N7, 60N01, 60N02, 60N05) for the
S5U1C62N51E1.
Note: Do not use the option data generated by the function and segment option generators for an Evaluation Board
other than the S5U1C62N51E1. Data created by the old function and segment option generators cannot be
used. It will cause a malfunction.
Switch
• RESET switch
This switch resets the CPU and starts the target program from page 01H, step 00H.
Controls
• OSC1 ADJ
This is the control for varying the CR oscillation frequency. This control is effective only when CR oscillation
is selected for the OSC1 oscillator type by mask option. The CR oscillation frequency can be checked with an
oscilloscope or other instrument by connecting to the test pin "CR-FREQ".
• VSVD
This is the control for varying the power supply voltage in simulation to check SVD operation. (Refer to
Section 6.2, "Differences from Actual IC".
FUSE
• FUSE1
This is 3 A tubular fuse for external power supply, and is blown off by current of 3 A or more.
