Configuration of Display Data Bit
Packed Pixel Method
For grayscale display, multiple bits are needed for one pixel. In the HD66522, two bits are assigned to one
pixel, enabling a four-level grayscale display.
One address (eight bits) specifies four pixels, and pixel bits 0 and 1 are managed as consecutive bits. When
grayscale display data is manipulated in bit units, one memory access is sufficient, which enables smooth
high-speed data rewriting.
The bit data to input to pin DB7, DB5, DB3 and DB1 become MSB and the bit data to input via pin DB6,
DB4, DB2 and DB0 are LSB.
