Note:
When perfoming a dot scroll with an extended driver, the maximum number or characters
per line decreases by quantity set by the dot scroll. For example, when the maximum
24-dot scroll quantity (4 characters) is used with 6-dot font width and 4-line display,
the maximum numbers of character is 20 – 4 = 16. Notice that in low power mode (LP = 1),
display shift and dot scroll cannot be performed.
6-dots font width mode (FW = 1)
4 line display mode (NW = 1)
