LED FLASHING CODES
PURPOSE: The led indicates the power mode,ocurred I
2
C error and On timer
INPUT:
- Current power mode
- I

C Errors
- On timer
Processing:
- If in STAND-BY mode and On timer in-active then switch LED off.
- If in STAND-BY and On timer active
set LED to blinking, (switch on and off at 1 Hz with a 50 % duty cycle).
- If in POWER-ON mode, switch LED on.
- If an I
2
C error occurred, let the LED blink at 1 Hz, 50 % duty cycle.
For the blinking times see the Table below.
Note:
Only when an I
2
C error occurs for a number of times, or for a number of seconds,
the I
2
C error is handled by the system (that is ,only then the set will go to stand-by,
the led starts blinking).
