4 General Description
4.1
4.2
This chip supports four bus widths, 8/9/16/18, for transporting 16 (565) or 18 (666) bits
data. In some setting mode of X_IM [5:0], data has to be segmented in several parts.
Once transferring start, the following rule of order must be kept:
All commands have 8 bits width with each bit has its own definition. Through command
issues, the coming data can be direct to register for system setting or memory for access.
Following shows how to issues a command in both 80-series and 68-series mode
