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.)
[Command format]
To specify the character code of CGROM and CGRAM continuously to the next address, specify only character
codes as follows.
The addresses of DCRAM are automatically incremented. Specification of an address is unnecessary.
