Description of Commands and Functions

1. DCRAM data write

(Specifies the addresses 00H to 1FH of DCRAM and writes the character codes of CGROM and CGRAM.)

DCRAM (Data Control RAM) has a 5-bit address to store the character codes of CGROM and CGRAM.

The character code specified by DCRAM is converted to a 5 × 7 dot matrix character pattern via CGROM or

CGRAM.

(The DCRAM can store 24 characters.)
