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)
Solved! Go to Solution.
According to your reply, PMIC_STBY_REQ signal is always controlled by i.MX6, also in this case.
Is this right?
