Question about SDB Schematic

[ko-hey]

Hi all

I want to know a purpose of using NC7SP125P5X.

NC7SP125P5X have been used for SABRE-SDB.

Please see a MCIMX6Q-SMART DEVICE BOARD schematic in P21.

I think it will be used for reset a PMIC by watchdog-timer.

Please tell me a purpose of using NC7SP125P5X.

Hi Igor

Thank you for your quick response.

As that case, I can't understand the reason why the C504 is needed.

Why C504 is needed ?
