About behavior of i.MX25 when Low was input into POWER_FAIL pin

[yuuki]

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,

Yuuki

Hello

 POWER_FAIL is an input pad, which is connected to ARM interrupt controller as IRQ30.

Please refer to i.MX25 RM, Table 3-1. So, when active, this signal can provide interrupt

event.

Have a great day,
Yuri
