Figure 2–3 shows the LCD configuration for the character generator. A character is configured in 5

7-dot
configuration.
The most significant bit (bit 7) of the data memory is not used by the character generator. Therefore, LCD dots,
corresponding to the most significant bit (R7 in 8-time-division, or R7 and R15 in 16-time-division), can be used for the
cursor or indicator display pattern, independently from the character generator.
The most significant bits are manipulated by a cursor manipulation command (WRCURS, CLCURS), etc.
