The functions of the LCD controller/driver in the 78K0/LC3 are as follows.
(1)
(2)
(3)
(4)
(5)
Note The four segment signal outputs (SEG0 to SEG3) and four common signal outputs (COM4 to COM7) are
The LCD driver voltage generator can switch external resistance division and internal resistance division.
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
Segment signal outputs: 22
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).
