Basic question about AUTO_RESTART sequence of i.MX28

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.
