PMIC PF8200 I2C register default/reset values

mathieu_reygner — Thu, 09 Jul 2026 15:25:06 GMT

I am using the PF8200 with an OTP configuration.

I need to load some registers by SCFW with new values to change the PMIC configuration.

The register bits which are not loaded by OTP values do not have default values specified in datasheet.

What are these values to know if it is useful or not to load all the registers not already loaded by OTP.

Thanks;

Hello,

Registers or bits that are not loaded from OTP are initialized to their default values after power-up. Therefore, it is not necessary to configure all non-OTP registers through SCFW unless you need values different from the default settings.

To determine whether additional initialization is required, please compare your desired configuration against the default register values.

Please see PF82 family I2C register Map

Hope this helps!

Thanks for quick answer.
I do not find any information about their default values after power-up.
Please, let me inform where I can find this information !

Could you please confirm which registers you are interested in?

For example, register 05 INT_MASK_1.

But all registers specified as OFF_TOGGLE.

Thanks.
