About precision for VDD_xxx_CAP of i.MX6Solo

Dear all,

 

Would you tell me about precision for VDD_xxx_CAP of i.MX6Solo?

- VDD_ARM_CAP
- VDD_SOC_CAP
- VDD_PU_CAP

 

The value of each VDD_xxx_CAP is as follows.
- VDD_ARM_CAP;1.225~1.400
- VDD_SOC_CAP;1.15V~1.125V
- VDD_PU_CAP;1.15V~1.125V

 

I understand that these values are values to be set in each Set points.(not measured voltage value)

Is my understanding correct?

 

In 996MHz operation,
When the Set Point of VDD_ARM_CAP is set to 1.225V, the measured voltage is 1.246V.

Is this correct operation?

 

How much is a precision(margin of error) for each VDD_xxx_CAP set points?

 

May I have advice?

Best Regards,
Yuuki
