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 (winfog).
• 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 (winsog).
• LCA ROM
This is the S1C60N15 peripheral circuit ROM.
■
Switch
• RESET switch
This switch resets the CPU and starts the target program from page 01H, step 00H.
■
FUSE
• FUSE1
This is 3 A tubular fuse for external power supply, and is blown off by current of 3 A or more.
■
Controls
• OSC3CR
This is the control for varying the OSC3 CR oscillation frequency. This control is effective only when
CR oscillation is selected for the OSC3 oscillator type by mask option. The CR oscillation frequency
can be checked with an oscilloscope or other instrument by connecting to pin 10 of the sub-board
connector.
Turning clockwise: High frequency
Turning counterclockwise: Low frequency
