Display Data RAM
The Display Data RAM stores pixel data for the LCD. It is a 128-column x 64-row addressable array as
shown in Figure 3. The 64 rows are divided into 8 pages of 8 lines. Data is read from or written to the 8
lines of each page directly through DB0 to DB7.
The microprocessor reads from and writes to RAM through the I/O buffer. Since the LCD controller oper-
ates independently, data can be written to RAM at the same time as data is being displayed, without caus-
ing the LCD to flick.
