Description of Commands and Functions
1, 9. DCRAM data write
(Specifies the address 00H to 0FH of DCRAM and writes the character code of CGROM and CGRAM.)
DCRAM (Data Control RAM) has a 4-bit address to store character code 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 16 characters.)
[Command format]
Note: To specify the character code of CGROM and CGRAM continuously to the next address, specify only
character code as follows.
The addresses of DCRAM are automatically incremented. Specification of an address is unnecessary.
X0 (LSB) to X3 (MSB): DCRAM addresses (4 bits: 16 characters)
C0 (LSB) to C7 (MSB): Character code of CGROM and CGRAM (8 bits: 256 characters)
