TAS3251EVM: .h file imported from PPC3 without description in slaa799a.pdf

Part Number: TAS3251EVM
Other Parts Discussed in Thread: TAS3251

Hello,

Our customer used PPC3 and imported .h file, but the Sub Address in the .h file isn't described by .

please refer to the purple block which didn't describe in the above application notes.

In addition, please refer to Address 13, each sub address have some other address which has no description, the red block has description but the NA without. So the question is that, does he could used this .h file to write registers? He tried to write the write co-efficients by I2C, but the results are not right.

Best regards

Hi Kailyn,

We do actually mention the Page 13 registers in the TAS3251 Process Flow App note:

I'm not sure what you mean by purple block?

Best Regards,

Hi Robert,

I am so sorry to forget to past the purple block. The purple registers also didn't describe in the application notes. Now I understand it is also describes in Table 7. Thank you very much for your reply.

Hello Kailyn,

The header file includes public coefficient in RAM and part of ROM. But not all registers are open to customer.

Is there any issue met in customer's side?

Hi Alix，

Thank you very much for your reply, does the whole header file have the written sequence? or if there is some notice should be paid attention?

Best regards
