DISPLAY DATA RAM (DDRAM)
The Display Data RAM stores pixel data for the LCD. It is 129-row (17 page by 8 bits) by 128-column addressable
array. Each pixel can be selected when the page and column addresses are specified. The 129 rows are divided into
16 pages of 8 lines and the 17th page with a single line (DB0 only). Data is read from or written to the 8 lines of each
page directly through DB0 to DB7. The display data of DB0 to DB7 from the microprocessor correspond to the LCD
common lines. The microprocessor can read from and write to RAM through the I/O buffer. Since the LCD controller
operates independently, data can be written into RAM at the same time as data is being displayed without causing
the LCD flicker.
Page Address Circuit
This circuit is for providing a Page Address to Display Data RAM shown in figure 8. It incorporates 4-bit Page
Address register changed by only the “Set Page” instruction. Page Address 16 is a special RAM area for the icons
and display data DB0 is only valid.
Line Address Circuit
This circuit assigns DDRAM a Line Address corresponding to the first line (COM0) of the display. Therefore, by
setting Line Address repeatedly, it is possible to realize the screen scrolling and page switching without changing
the contents of on-chip RAM as shown in figure 8. It incorporates 7-bit Line Address register changed by only the
initial display line instruction and 7-bit counter circuit. At the beginning of each LCD frame, the contents of register
are copied to the line counter which is increased by CL signal and generates the line address for transferring the
128-bit RAM data to the display data latch circuit. When icon is enabled by setting icon control register, display data
of icons are not scrolled because the MPU can not access Line Address of icons.
