ST33TPHF2XI2C How to access TPM's GPIOs?

[aaflores]

Hi,

 

I am working on integrating the TPM ST33TPHF2XI2C into our platforms and we noticed that there are two GPIOs in the TPM chip. The datasheet says the following:

 

 

The GPIO function could be modified by activating GPIOs mapped on the NV storage index feature.

 

 

Is there any information/documentation where it is indicated which NV storage index is the one required for this function? or any additional information about how to access and or use the GPIOs?
