EM65565A
Display Data RAM (DDRAM)
The DDRAM is a RAM that stores the dot data for the display. It has a 65
×132 bits. It is
possible to access the desired bit by specifying the page address and the column address.
The D7 to D0 display data from the MPU corresponds to the LCD common direction. There
are few constraints at the time of display data transfer when multiple EM65565A chip is used.
Thus and display structures can be created easily and with a high degree of freedom.
Moreover, reading from and writing to the display RAM from the MPU side is performed
through the I/O buffer, which is an independent operation from signal reading for the liquid
crystal driver. Consequently, even if the DDRAM is accessed asynchronously during LCD, it
will not cause adverse effects on the display (such as flickering).
