(5-4) Ope-pane circuit
The ope-pane circuit consists of 4 LEDs and 4 switches.
Each LED is directly driven by the Custom IC (IC11) and each switch signal is input to the
Custom IC (IC11). (The following shows the simplified circuit diagram.)

(5-5) USB I/F control circuit
The USB control circuit interfaces with the USB (Universal Serial Bus).
NAND gates (IC19) and transistor DTR5 consist of a USB connection detecting circuit.
When USB connector is connected, pin 1 of CN20 (USBVCC) is at “High” level. The
detection circuit detects this level and output a UBINTP pulse to the CPU.
