Error conditions
Blink codes are used to signal warnings or error states (When S1 and S2 blink 
together, you see blinking orange):
• S1 means green half of LED
• S2 means red half of LED
• Example: LLC not ready  S1 (3 blinks) + S2 (5 blinks): 3 orange blinks and 
afterwards 2 red blinks
Video mode error: These are error modes according IIDC specification: 
Vmode_Error_Status register (wrong settings of video mode, format, frame rate 
and ISO settings).
Format 7 error: see Format 7 register description of IIDC specification.
