TAS2563YBGEVM-DC: Relationship between various PPC3 settings and register map

Part Number: TAS2563YBGEVM-DC
Other Parts Discussed in Thread: TAS2563

Tool/software:

Hi, some enginners.

We are currently working on various sound quality adjustments, protection functions, communication settings, etc. within PPC3.

I was trying to create materials for the FW team using the settings and register map as reference, but the register map was still at the default values.

There are 3 things that concern me here.

1. How are the settings in each item of PPC3 (Device control, Tuning, etc.) reflected in the register map?

2. Does the setting within PPC3 cover all the registers?

3. Is there a way to manipulate the register map directly, rather than through the PPC3 settings? Is this possible with Direct I2C? If so, please share the method.

These are the three points. I would appreciate your response.

Regards,

Fumiya.

    Hi Fumiya,

    1. The register map structure is complex. Some of the settings in the GUI affect a single bit, others affect multiple bits and others may write to several bytes. It depends on the feature being controlled.
    2. PPC3 configuration will change any required registers.
    3. It is recommended using PPC3 as it will do any required calculations whenever a feature is modified, eg. changing the boost max level will not only affect a single register.
      I would suggest getting the configuration you want to test using PPC3, then you can generate an I2C script to write directly, if that helps.

    Hi, Ivan.

    Thanks for your answer.

    I will proceed while focusing on the settings in PPC3.

    I have one question. Is it correct to say that most smart amplifiers, including the TAS2563, are based on the assumption that they will be developed using PPC3?

    It would be sufficient for us to know your company's understanding on this matter.

    Best Regards,

    Fumiya.

    Hi Fumiya,

    Correct, using PPC3 would result in best performance configuration.
