38C3 Group
• Apply voltage of 2.5 V to 5.5 V to VCC, and 0 V to VSS.
• Reference voltage input pin for A-D converter.
• GND input pin for A-D converter.
• Connect to VSS.
• Reset input pin for active “L.”
• Input and output pins for the main clock generating circuit.
• Feedback resistor is built in between XIN pin and XOUT pin.
• Connect a ceramic resonator or a quartz-crystal oscillator between the XIN and XOUT pins to set the
oscillation frequency.
• If an external clock is used, connect the clock source to the XIN pin and leave the XOUT pin open.
