Double-Height Display
The HD66717 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 25. All the standard font characters stored in the CGROM and
CGRAM can be doubled in height, providing an easy-to-see display. Note that there should be no space
between lines for double-height display (Figure 43).
