Double-height Display Control
DL3-1:
Specify the double-height display for a given line. When DL1 = 1, the first line is displayed at
double height. When DL2 = 1, the second line is displayed at double height. When DL3 = 1, the third line
is displayed at double height. Double-height display of multiple lines is possible. When the fourth line is
displayed at double height, set CEN to 1, shift the display position towards the center by one line, and set
DL3 to 1. For details, see the Double-height Display section.
