Instruction code:
The “BF” bit (DB7) of this instruction tells whether the ML9044A is busy in internal operation (BF = “1”) or
not (BF = “0”).
When the “BF” bit is “1”, the ML9044A cannot accept any other instructions. Before inputting a new
instruction, check that the “BF” bit is “0”.
When the “BF” bit is “0”, the ML9044A outputs the correct value of the address counter. The value of the
address counter is equal to the DDRAM, ABRAM or CGRAM address. Which of the DDRAM, ABRAM and
CGRAM addresses is set in the counter is determined by the preceding address setting.
When the “BF” bit is “1”, the value of the address counter is not always correct because it may have been
incremented or decremented by 1 during internal operation.

Instruction code:
A character code (P7 to P0) is read from the DDRAM, Display-ON data (P7 to P0) from the ABRAM or a
character pattern (P7 to P0) from the CGRAM.
The DDRAM, ABRAM or CGRAM is selected at the preceding address setting.
After data is read, the address counter (ADC) is incremented or decremented as set by the Entry Mode Setting
instruction (see 3).
Note: Conditions for reading correct data
(1)
The DDRAM, ABRAM or CGRAM Setting instruction is input before this data read instruction is input.
(2)
When reading a character code from the DDRAM, the Cursor/Display Shift instruction (see 5) is input
before this Data Read instruction is input.
(3)
When two or more consecutive RAM Data Read instructions are executed, the following read data is
correct.
Correct data is not output under conditions other than the cases (1), (2) and (3) above.
Note:
The execution time of this instruction is 37
s at an oscillation frequency (OSC) of 270 kHz.
