3,B. ADRAM data write
(ADRAM writes symbol data)
ADRAM (Additional Data RAM) has a 1-bit address to store symbol data.
Symbol data specified by ADRAM is directly output without CGROM and CGRAM.
(The ADRAM can store 1 type of symbol patterns for each digit.)
The terminal to which the contents of ADRAM are output can be used as a cursor.
[Command format]
To specify symbol data continuously to the next address, specify only character data as follows.
The address of ADRAM is automatically incremented. Specification of addresses is unnecessary.
A character code setup of 24-Digit is completion in the above work.
Furthermore, you have to specify the character codes of a dummy to be ADRAM and 18H-1FH to perform a
character code setup from ADRAM address 00H continuously.
(In order to carry out the increment of the address of ADRAM automatically and to set a ADRAM address to
00H.)
