Note 1: These registers are implemented but not used as LCD data registers in 64-pin devices. They may be used
as general purpose data memory.

For LCDDATA0 through LCDDATA5: n = (8x), y = 0
For LCDDATA6 through LCDDATA11: n = (8(x â 6)), y = 1
For LCDDATA12 through LCDDATA17: n = (8(x â 12)), y = 2
For LCDDATA18 through LCDDATA23: n = (8(x â 18)), y = 3
1 = Pixel on (dark)
0 = Pixel off (clear)
Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
â1â = Bit is set
U = Unimplemented bit, read as â0â
â0â = Bit is cleared x = Bit is unknown
