TAS5825P: Substitution from TAS5852M

Tool/software:

Hello,

There are some differences in setting resistor.(Between TAS5825M and TAS5825P)


For example,
TAS5825M has SAP_CTRL3 register(35h), and TAS5825P doesn't have.

I'd like to know the behavior when I send a commant to SAP_CTRL3(35h) register to TAS5825P(which does not have SAP_CTRL3 register).

(substitute from TAS5825M to TAS5825P without changing software) 

Is this SAP_CTRL3 setting ignored for TAS5825P?
Or is there a possibility that sending a command to 35h to TAS5825P may cause a malfunction?

regards,
