Description of Commands and Functions
1,9. DCRAM data write
(Writes the character code of CGROM and CGRAM.)
DCRAM (Data Control RAM) has a 5-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 24 characters.)
[Command format]
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.
A character code setup of CGROM to 24-Digit and CGRAM is completion in the above work.
Furthermore, you have to specify the character codes of a dummy to be DCRAM and 18H-1FH to perform a
character code setup from DCRAM address 00H continuously.
(In order to carry out the increment of the address of DCRAM automatically and to set a DCRAM address to
00H.)
