Part Number: TAS5411-Q1
Questions about status and load diagnostic register (0x02)
In the evaluation environment of TAS 5411 EVM User's Guide page 3,when I read the value of Status and Load Diagnostic Register (0x02) from EVM, the normal value(80h) is returned.
On the other hand, when I tried in an environment using the evaluation board and our 5V microcomputer, different values of "FFh" is returned.
If you know the reason why the value of "FFh" is returned, please let me know.
Thank you for your help.

Hi Orobianco,I see a couple of things and I wonder if you can clear this for me:On the "NG" graph, it looks like the read has a NACK on the 9th clock cycle. Can you confirm?Also, how is the ground connected to the EVM and the MCU?Is there also ground pin close to I2C bus on the MCU connected to ground pin near I2C bus of the TAS5421?Is S1 on "OPERATION" position?

I'm checking to see if you have heard back from your customer in regard to the standby pin control. Just let us know when you have the information. Thank you.
Best regards, Tuan
