19. Display Unit (DU)
YC Data Contention: The display unit (DU) has only one YC-RGB conversion circuit internally,
and so YC-RGB conversion cannot be performed simultaneously for two or more planes. When
there are pixels requiring YC-RGB conversion on two or more planes simultaneously, the pixels
on the uppermost plane are YC-RGB converted, and the lower plane is not displayed.
Figure 19.8 describes YC-RGB conversion when the data for three planes is in YC format.
