ADDRESS COUNTER (AC)
The address counter is used to assign the Display Data RAM (DDRAM) Address and the Character
Generator RAM (CGRAM) Address. When an Address information is written into the Instruction
Register (IR), this Address information is sent from the Instruction Register to the Address Counter. At
the same time, the nature of the Address (either CGRAM or DDRAM) is determined by the instruction.
After writing into or reading from the DDRAM or CGRAM, the Address Counter is automatically
increased or decreased by 1 (for Write or Read Function). It must be noted that when the RS pin is set to
"0" and R/WB is set to "1", the contents of the Address Counter are outputted to the pins -- DB0 to DB6.
DISPLAY DATA RAM (DDRAM)
The Display Data RAM (DDRAM) is used to store the Display Data which is represented as 8-bit
character code. The Display Data RAM supports an extended capacity of 80 x 8-bits or 80 characters.
The area in the DDRAM which are not used for display can be used as General Data RAM. For more
details, please refer to the sections below.
The Display Data RAM Address (A
DD
) is set in the Address Counter as a hexadecimal.
