Hi community,

 

I have a basic question about AUTO_RESTART sequence of i.MX287.

I think that AUTO_RESTART = 1, after Power Down, it will restart if PSWITCH is a MID or HIGH condition.

If PSWITCH is LOW (pulled down to GND by 100KΩ), it will keep Power Down.

 

   PSWITCH | AUTO_RESTART = 1 
   LOW          : Power down 
   MID            : Restart 
   HIGH         : Restart 

 

Is it correct?

If so, How does it work if brownout condition is detected.

 

   PSWITCH | AUTO_RESTART = 1, DCCD_BAT BROWNOUT
   LOW          : Power down 
   MID            : Restart 
   HIGH         : Restart 

 

Is it correct?

 

Best regards,

Ishii.
