11.16.2 LCD Display RAM Organization
Display data are stored to the display data area in the external data memory.
The display data which stored to the display external data area (address 0000H-003FH) are read automatically and
sent to the LCD driver by the hardware. The LCD driver generates the segment signals and common signals in
accordance with the display data and drive method. Therefore, display patterns can be changed by only overwriting
the contents of the display external data area with a program.
Figure 11-89 shows the correspondence between the display external data area and the COM/SEG pins. The LCD is
turned on lights when the display data is “1” and turned off when “0”.
