3.15 Display Character Control Command

This command specifies the character data to be written to the video RAM, blinking data, and character color.

When inputting this command, turn ON LC oscillation (if the oscillation is OFF, characters cannot be written to the

video RAM).

This command is a 2-byte successive command. To write character data successively without changing the blinking

data, character color, and character address bank, the second character and those that follow can be input in the

abbreviated form by using only the low-order 8 bits (D7 through D0). In this case, the write column address is

automatically incremented (If a character is written to the 23rd column, the next write address is automatically

incremented to column 0 (leftmost) on one row below. If characters have been written to the 23rd column on the 11th

row, the next write address is automatically incremented to column 0 on row 0).
