Note 1: Bits<7:1> of these registers are not implemented in PIC18F6XK90 devices. Bit 0 of these registers
(SEG32Cy) is always implemented.

For registers, LCDDATA0 through LCDDATA5: n = (8x), y = 0
For registers, LCDDATA6 through LCDDATA11: n = (8(x â 6)), y = 1
For registers, LCDDATA12 through LCDDATA17: n = (8(x â 12)), y = 2
For registers, LCDDATA18 through LCDDATA23: n = (8(x â 18)), y = 3
1 = Pixel on (dark)
0 = Pixel off (clear)
