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.
3. ADRAM data write
(specifies address of ADRAM and writes symbol data)
ADRAM (Additional Data RAM) has a 2-bit address to store symbol data.
Symbol data specified by ADRAM is directly output without CGROM and CGRAM.
(The ADRAM can store 2 types of symbol patterns for each digit.)
The terminal to which the contents of ADRAM are output can be used as a cursor.
