Dear Sir,

     I have some confuse on the concept of iMX6 graphic window and full plane alpha blending, as you can set Graphic Window as full plane in the register "  IPUx_DP_COM_CONF_SYNC" ( set GWSEL=0;)



But the in the register below, it says,

"GWAV - Graphic Window Alpha Value

Defines the alpha value of graphic window used for alpha blending between graphic window and full

plane. The Value the number that writing to GWAV register. "

How about if  graphic window == full plane? how to blend??
