The ABRAM addresses are valid until CGRAM or DDRAM addresses are set.
The CPU writes or reads character patterns starting from the one represented by the ABRAM
address bits H to H set in the instruction code at that time.
4
0
The ABRAM address represented by bits H4 to H0 (binary) should be in the range “00” to “13”
in hexadecimal.
If an address other than above is input, the ML9041 cannot properly write a character code in or
read it from the DDRAM.
Note:
The execution time of this instruction is 37 ms at an oscillation frequency (OSC) of 270
kHz.
