The Layer Scale Factor register determines the scaling factor that is applied before blending this layer with the underlying layer. Scale factors of 1x, 2x, and 4x are supported.
• 0 = No scaling
• 1 = 2x scaling (horizontally and vertically)
• 2 = 4x scaling (horizontally and vertically)
Layer scaling is only supported when the Enable Scaling field in the Vivado IDE is enabled for a particular layer.
