Part Number: TAS5782M


Hi,

Our customer found the registers which aren't mentioned in the application note "TAS5782M Process Flows " if dumping the DSP memory.
So, could you please tell me that registers in detail as below ?

    Hi Kato-san,

    Parameters shown in PPC3 GUI can be found in "TAS5782M Process Flows ". Some registers are not open to customer, hence you may not be able to find them in the applicaiton note.
    Hence, can you point out which register cencerning opening parameters in PPC3 GUI cannot be found in applciaton note? I will explain to you one by one.

    Hi Alix-san,

    Thank you for your prompt reply.

    I would pick up the registers which aren't mentioned in the application note, but it seems that procedural repetition commands are also included.
    So, could you please tell me the meaning of each one ?

    Best regards,
    Kato

    Hi Kato-san,

    You can also refer to register map part of datasheet for register descriptions.
    If any other registers bother you, please pick them up and I will explain to you if necessary.

    Hi Alix-san,

    Thank you for the information.

    I would like to confirm just in case, is 2.1 mode memory map same with 2.0 mode memory map for process flow3 ?

    Best regards,
    Kato
