LCD Display Memory
The phone controller provides an area on embedded data memory for LCD display. 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 1 or 0 is written to the corresponding bit of the display memory, respec-
tively.AlloftheLCDdisplaymemoriesarewithrandomvaluesafterthepoweronresetandunchangedafterotherreset
