• LPT: Line Pattern
Sets 16-bit 1D pattern or 4 x 4-bit 2D pattern for line drawing.
In 1D pattern drawing, LPT[0] is the starting point of the pattern. After each operation, LPT will rotate one bit to the right. In
2D pattern drawing, the bit pattern does not rotate. The operation is determined on the last 2 bits of X and Y addresses as
shown in the table below.
