When data is written into the display data area it is automatically read by the LCD driver which then generates the corresponding LCD driv- ing signals, to turn the display On or Off, a ²1² or ²0² is written to the corresponding bit of the display memory, respec- tively. All of the LCD display memories are with random values after the power on reset and unchanged after other reset conditions.
