Display Data RAM (DDRAM)

The Display Data RAM stores pixel data for the LCD. It is 64-row by 128-column addressable array. Each pixel can be selected when the page and column addresses are specified. The 64 rows are divided into 8 pages (Page 0~Page 7) of 8lines . Data is written to the 8 lines of each page directly through D0 to D7. The display data of D0 to D7 from the microprocessor correspond to the LCD common lines. The LCD controller and MPU interface operate independently, data can be written into RAM at the same time when data is being displayed without flicker on LCD.

Page Address Circuit

This circuit is for providing a Page Address to Display Data RAM. It incorporates 4-bit Page Address register changed by only the “Set Page Address” instruction. The Page Address must be set before accessing DDRAM content. Page Address “8” is a special RAM area for the icons and display data D0 is only valid.

Column Address Circuit

Column Address Circuit has a 8-bit preset counter that provides Column Address to the Display Data RAM (DDRAM). The DDRAM column address is specified by the“Set Column Address ” command. The specified column address is incremented (+1) with each display data read/write access. This allows the MPU display data to be accessed continuously. Control flag MY can invert the output order of the COM pads. And the MX flag makes it possible to invert the relationship between the Column Address and the SEG outputs. It is necessary to rewrite the display data into DDRAM after changing MX flag setting. Please refer to ST7565 datasheet.
