The LCD display memory are lo- cated at bank 1BH and can be read and written to, only by indirect addressing mode using MP1. 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.
