HD66724/HD66725
Double-Height Display
The HD66724/HD66725 can double the height of any desired line from the first to third lines. A line can be
selected by the DL3 to DL1 bits as listed in table 41. All the standard font characters stored in the CGROM
and CGRAM can be doubled in height, allowing easy recognition. Note that there should be no space
between the lines for double-height display (figure 50).
