Note The four segment signal outputs (SEG0 to SEG3) and four common signal outputs (COM4 to COM7) are
• Displaying an A-pattern area (lower four bits)
• Displaying a B-pattern area (higher four bits)
• Alternately displaying A-pattern and B-pattern areas (blinking display corresponding to the constant-period
Item
interrupt (INTRTC) timing of the real-time counter (RTC))
The LCD driver voltage generator can switch internal voltage boosting method, capacitor split method, and
external resistance division method.
Automatic output of segment and common signals based on automatic display data memory read
Six different display modes:
• Static
• 1/2 duty (1/2 bias)
• 1/3 duty (1/2 bias)
• 1/3 duty (1/3 bias)
• 1/4 duty (1/3 bias)
• 1/8 duty (1/4 bias)
Six different frame frequencies, selectable in each display mode
The reference voltage to be generated when operating the voltage boost circuit can be selected from 20 stages
(contrast adjustment).
The data display of the LCD display data memory can be selected from three types.
78K0R/LF3:
78K0R/LG3:
78K0R/LH3:
alternate-function pins. COM4 to COM7 can be used only when eight-time-slice mode is selected by the setting
of the LCD display mode register (LCDM).
