3, B. ADRAM data write
(specifies address 00H to 0FH of ADRAM and 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]
Note: 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.
X0 (LSB) to X3 (MSB) :
ADRAM addresses (4 bits: 16 characters)
C0 :
Symbol data (1 bit: 1-symbol data per digit)
