•Reference voltage input pin for A-D converter and D-A converter.
•GND input pin for A-D converter and D-A converter.
•Connect to VSS.
•Reset input pin for active “L”.
•Input and output pins for the main clock generating circuit.
•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. A
feedback resistor is built-in.
•Input 0 ≤ VL1 ≤ VL2 ≤ VL3 voltage.
•Input 0 – VL3 voltage to LCD. (0 ≤ VL1 ≤ VL2 ≤ VL3 when a voltage is multiplied.)
•External capacitor pins for a voltage multiplier (3 times) of LCD control.
•LCD common output pins.
•COM2 and COM3 are not used at 1/2 duty ratio.
•COM3 is not used at 1/3 duty ratio.
•LCD segment output pins.
•8-bit I/O port.
•CMOS compatible input level.
•CMOS 3-state output structure.
•Pull-up control is enabled.
•I/O direction register allows each 8-bit pin to be pro-
grammed as either input or output.
