Hello,

 

We are searching a way to detect the loss of CLOCK INPUT CLKIN Signal through the I2C Port.

 

- Is there a register related to this system failure ?

 

By experimentation, we observed that 0xBA (SD brightness detect) et 0xBB (field count) register are stuck on the last value when CLKIN is not present.

 

-What is the purpose of these registers ?

- Do you think that a detection of change on these registers can be used for failure detection ?

- Is there a risk of false detection ?

 

Regards,

 

Perry
