8. Cursor and Blink Control Circuit

This circuit generates the LCD cursor and blink.

This circuit is under the control of the CPU program. The display of the cursor or blink on the LCD

is made at a position corresponding to the DD RAM address set to the ADC.

The figure below shows an example of the cursor and blink position when the value of the ADC

is set at "07" (hex.).

Cursor and blink position

(Note)

The cursor and blink are displayed even when the CG RAM address is set to the ADC.

For this reason, it is necessary to inhibit the display of the cursor and blink while the

CG RAM address is set to the ADC.
