这些regulators输出的值都是您选择的或者自己预定的,AMUX读出来的值您比较下就知道了,但是OTP寄存器里面的数值一般不再客户端支持读取。

这些regulators输出的值是硬件还是软件设定的?

Do you know the value you set about these regulators?

Isn't the regulator configured by OTP?Are these voltages related to the Main OTP_REGISTERS configuration?

Okay,Thank you for your reply,I have another question,I read some voltage values from the M_AMUX register as follows: VDDIO voltage = 3.23V, VBUCK1 voltage = 1.25V, VBUCK3 voltage = 2.32V, VPRE voltage = 3.29V, VBOOST voltage = 5.78V, etc. How do I know these voltage values are correct.

Thanks, and I read some voltage values ​​through M_AMUX register. For example: VDDIO voltage = 3.23V, VBUCK1 voltage = 1.25V, VBOOST voltage = 5.78V.So, how do I know that these voltage values ​​are correct.
