3. ADRAM data write
(Specifies the addresses 00H to 1FH of ADRAM and writes symbol data.)
ADRAM (Additional Data RAM) has a 5-bit address to store symbol data.
Symbol data specified by ADRAM is directly output without CGROM and CGRAM.
(The ADRAM can store 4 types 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 symbol data as follows.
The address of ADRAM is automatically incremented. Specification of addresses is therefore unnecessary.
