MediaLBn System Data Configuration Register (MLBn_SDCR)
MediaLBn System Data Configuration Register (MLBn_SDCR) is a register to receive the system channel
data for the MediaLB frame. SDCR is updated for each MediaLB frame. System software must read
MLBn_SDCR before the start of the next MediaLB frame to prevent the current frame data from being
lost.

[bit31:0] MSD[31:0] : MediaLB System Data
This register is loaded with the data from MLBn_MLBDAT during the System Channel quadlet.
The System Data Configuration register (MLBn_SDCR) allows system software to receive control
information from the MediaLB Controller.
MLBn_SDCR is updated once per frame by hardware during the MediaLB System Channel. System
software must read MLBn_SDCR before the start of the next MediaLB frame to prevent the current frame
data from being lost.
