The state of PMIC_ON_REQ

Dear Sir

 

I would like to confirm the state of PMIC_ON_REQ.

Customer will build the Chip reset scheme like Figure 60-1(IMX6SDLRM Rev.4 P5020).

 

The PMIC_ON_REQ will be High("1") when the state of FSM is ON.

Q1.

If VDD_SNVS_IN is still powered but other power supply is cut off, is the PMIC_ON_REQ remaining in the state of 1?

 

Best Regards,

Eishi SHIBUSAWA

Q1. If VDD_SNVS_IN is still powered but other power supply is cut off, is the PMIC_ON_REQ remaining in the state of 1?
