The functions of the LCD controller/driver in the <strong>RL78</strong>/<strong>D1A</strong> are as follows.<br />

(1) The LCD driver voltage generator uses internal resistance division method.<br />

(2) Automatic output of segment and common signals based on automatic display data memory read<br />

(3) Three different display modes:<br />

• Static<br />

• 1/3 duty (1/3 bias)<br />

• 1/4 duty (1/3 bias)<br />

(4) Six different frame frequencies, selectable in each display mode<br />

(5) R5F10CGx/R5F10DGx: Segment signal outputs: 27 (SEG0 to SEG7, SEG9, SEG14 to SEG15,<br />

SEG24 to SEG27, SEG29 to SEG35,<br />

SEG40 to SEG44)<br />

Common signal outputs: 4 (COM0 to COM3)<br />

R5F10CLx/R5F10DLx: Segment signal outputs: 39 (SEG0 to SEG9, SEG14 to SEG19,<br />

SEG21, SEG23 to SEG44),<br />

Common signal outputs: 4 (COM0 to COM3)<br />

R5F10CMx/R5F10DMx: Segment signal outputs: 48 (SEG0 to SEG47),<br />

Common signal outputs: 4 (COM0 to COM3)<br />

R5F10TPx/R5F10DPx: Segment signal outputs: 53 (SEG0 to SEG52),<br />

Common signal outputs: 4 (COM0 to COM3)<br />
