Hi community,


I want to confirm about i.MX6 PMIC_STBY_REQ behavior.

Actually, PMIC_STBY_REQ of i.MX6D is tied to STANDBY pin of MMPF0100 on our custom board.

And PMIC_STBY_REQ line is changed to high level when i.MX6D is in low power mode and PMIC_ON_REQ (tied to PWRON pin of MMPF0100) is low.

Then, I want to know which chip (i.MX6D or MMPF0100) pulls PMIC_STBY_REQ line to high.

Could you let me know it?

(e.g. i.MX6D SNVS pulls the line to high, MMPF0100 internal pull-up resistor changes it high)
