Dear all,


We have a question about the function of the POWER_FAIL pin(T19 pin) of i.MX25.


The following is explained in the data sheet.

"An interrupt from PMIC, which should be connected to a low-battery detection circuit."


However, I was not able to find detailed explanation.


When T19 pin of i.MX25 is used as POWER_FAIL_INT function,
would you tell me the operation of i.MX25 when Low signal was input into this pin?
(When Low signal is input into this Pin, I want to know the behavior of i.MX25)


Best Regards,
