2. Set Character Pitch: (Execution time: 4 µs) Vp indicates the number of vertical dots per character. The

space between the vertically-displayed characters is included in the determination. This value is meaningful

only during character display (in the character mode) and becomes invalid in the graphic mode.

Hp indicates the number of horizontal dots per character in display, including the space between

horizontally-displayed characters. In the graphic mode, the Hp indicates the number of bits of 1-byte display

data to be displayed.

There are three Hp values (Table 1).
