This is most likely a valid SOG signal. 4 HSYNC1 Activity See HSYNC0 Activity description 5 VSYNC1 Activity See VSYNC0 Activity description 7:6 SOG1 Activity See SOG0 Activity description 0x03 CH2 and CH3 Activity Status, (read only) 0 HSYNC2 Activity See HSYNC0 Activity description 1 VSYNC2 Activity See VSYNC0 Activity description 3:2 SOG2 Activity See SOG0 Activity description 4 HSYNC3 Activity See HSYNC0 Activity description 5 VSYNC3 Activity See VSYNC0 Activity description 7:6 SOG3 Activity See SOG0 Activity description ISL51002 |
