Address Counter (ADC)
The address counter provides a read/write address for the DDRAM, ABRAM or CGRAM and also provides a
cursor display address.
When an instruction code specifying DDRAM, ABRAM or CGRAM address setting is input to the pre-defined
register, the register selects the specified DDRAM, ABRAM or CGRAM and transfers the address code to the
ADC. The address data in the ADC is automatically incremented (or decremented) by 1 after the display data is
written in or read from the DDRAM, ABRAM or CGRAM.
The data in the ADC is output to DB0(SO) to DB6 when RW/SI = “H”, RS0/CSB = “L”, RS1 = “H” and BF = “0”.
Timing Generator
The timing generator generates timing signals for the internal operation of the ML9042 activated by the instruction
sent from the CPU or for the operation of the internal circuits of the ML9042 such as DDRAM, ABRAM,
CGRAM and CGROM. Timing signals are generated so that the internal operation carried out for LCD displaying
will not be interfered by the internal operation initiated by accessing from the CPU. For example, when the CPU
writes data in the DDRAM, the display of the LCD not corresponding to the written data is not affected.
