When this command is accepted, the column register and then row register are reset to the Start Column/ Start
Row positions.
The Start Column / Start Row positions are different in accordance with MADCTL setting.
Then D [17:0] is read back from the frame memory and the column register and the row register incremented.
Frame Read can be stopped by sending any other command.
“Display Data Format” for color coding(18 bit cases), when there is used 8,9,16 or 18 data lines for image data.
X = Don’t care
