TAS6684Q1EVM: Book 0x64

Other Parts Discussed in Thread: TAS6684-Q1

Hello,

I'm developing a driver for the TAS6684-Q1. While using the GUI and EVM, I saw on the i2c output console that there were a significant number of writes to page 1 of book 0x64. I was hoping to find out more about book 0x64 and what these writes accomplish, as I can't seem to find any documentation about book 0x64. And does my driver need to perform these same writes to book 0x64 while initializing the TAS6684? I've attached a screenshot of the i2c console output.

Thank you!

Yes, kindly write into all of the registers.

They are to fix an issue, that discovered at very late stage. DSP may get stuck during power up, makes no audio output. The script could avoid this situation.

Thanks! Is there any documentation you'd be able to provide about book 0x64 and those writes?

Antonio,

It is something we have to follow GUI. those are DSP firmware codes, i don't have detailes on documentation.
