How to control PMIC_STBY_MODE_B pin?

[harry_choi]

Hello Community,

Is there any document or example to control PMIC_STBY_MODE_B pin?

I would like to test sleep mode on S32G.

So, is desserting PMIC_STBY_MODE_B pin mandatory for sleep and wakeup test?

Thanks,

Harry

PMIC_STBY_MODE_B is an output  signal which is asserted when the S32G enters standby mode to inform the PMIC. It is negated when the device detects a wake-up event. Details how to enter standby mode can be found in the AN12952 application note, look at section 4.3.

Dear Bulat,

Thanks for your reply.

I already read it but there is no explanation about PMIC_STBY_MODE_B pin.

Is it deasserted automatically if main core goes into standby mode?

So, is there no need to control the pin by software?

Thanks,

Harry

Yes, it is asserted (low level) automatically if main core goes into standby mode.

There is no software control of this pin.

Dear Bulat,

Thanks for your quick response.

So, per your reply, I recognize the standby status if PMIC_STBY_MODE_B pin is deasserted.

Is that right?

Then if I call Mcu_SetMode(SOC_STANDBY) function then the SoC will go into standby mode?

Thanks,

Harry
