2.4.3 Rotation Processing in Block
The copy controller rotates the rectangle area specified by the host CPU, and copies it into an area of the copy
destination.
C data when rotating 90
° or 270° is thinned out and its position is adjusted.
<<Rotation angles>>
Clockwise rotation: 0
°, 90°, 180°, 270°
<<Host CPU specification contents>>
Rectangle area start address of copy source (Xfrom_adrs, Yfrom_adrs)
Rectangle area size of copy source (Xsize, Ysize)
Rotation angle (Angle)
Start address of copy destination (Xto_adrs, Yto_adrs)
<<Rectangle specification restriction items>>
