The SCDC Controller Software allows automatic control of the SCDC
registers. For the SCDC Controller Software to appear (as shown in
Figure 23), click ‘Tools > SCDC Controller’.

HDMI specification
• to read the Character Error Detection from the SCDC register
• to read the VSDB (Vendor-Specific Data Block) to check the SCDC
availability
