5. Layer 0 and 1 (i.e., safety layer) in safety mode does not supports blending or luminance offset.
12.7.2 Features
• SC support area modes mentioned in Table 12-65
• Supports calculation of CRC on the pixel value only
• CRC is calculated with the initial value as 32’h000000000
• CRC does not support:
– Any modification of input bytes
– Any modification of the output CRC value before reporting.
• When PDI is enabled with the Layer 0 and 1 (safety enabled) in a single sector, then PDI would act
as BG layer and Layer 0 as a FG Layer.CRC would be calculated over a single L0 Layer.
