Cursor/Blink Control Circuit
This circuit generates the cursor and blink of the LCD.
The operation of this circuit is controlled by the program of the CPU.
The cursor/blink display is carried out in the position corresponding to the DDRAM address set in the ADC
(Address Counter).
For example, when the ADC stores a value of “07” (hexadecimal), the cursor or blink is displayed as follows:
0
DB6
DB0
0
111
7
0
00 01 02 03 04
07 08

Note:
The cursor or blink is also displayed even when a CGRAM or ABRAM address is set in
the ADC. Therefore, the cursor or blink display should be inhibited while the ADC is
holding a CGRAM or ABRAM address.
