3) Contrast Adjusting Data Read

This instruction reads contrast adjusting data (G4 to G0) from the contrast register.

Note:

The execution time of this instruction is 37 ms at an oscillation frequency (OSC) of 270

kHz.

4) ABRAM Address Setting

This instruction sets the character data corresponding to the ABRAM address represented by the

bits H4 to H0 (binary).

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 H4 to H0 set in the instruction code at that time.

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 ML9044 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.
