#define CLEAR_SCREEN 0x01 // This constant represents the command to clear the display, setting the Accumulator Control (AC) to 00H.

#define DISPLAY_ON 0x0c // Activates display functionality, including displaying a cursor and highlighting its position in white.
#define DISPLAY_OFF 0x08 // Deactivates display functionality, turning off the display and cursor.
#define CURSE_DIR 0x14 // Represents cursor movement to the right: AC = AC + 1 (incrementing the Accumulator Control).
#define SET_CG_AC 0x40 // Used for setting the Accumulator Control (AC), with a range from 00H to 3FH.
