Hello, I belong to distributor of Freescale Japan.


I have a question about i.MX6 external 32kHz detection.

Please see my questions below.



When i.MX6 external 32kHz clock detection circuit reset?

If you can, could you let me know what is a trigger to reset it?



Could you let me know the timing when i.MX6 detect 32kHz external clock and changes the clock source from internal 40kHz to external 32kHz?




Related to Q2, what is happen if 32kHz starts oscillation when i.MX6 detects POR_B releasing with internal 40kHz?

i.MX6 changes the clock source to 32kHz immediately?

Actually, we warry whether i.MX6 can preserve the POR_B relase detection when 32kHz starts oscillation this timing.
