I'm attempting to configure the TWL4030 in "Mode 2" - one Audio + one Voice

When I attempt to configure the OPTION Register, I can't set any of the Audio Enable bits (0, 1, 5, 6 or 7).

Am I missing something?

Is this a bug?

Are there registers in the Power or Clocking sections of the TWL4030 / TSP65950 IC's that need to be configured before you can enabled the Audio bits (0,1,5,6,7) of the OPTION register?

Did a bit of testing - it looks like the Audio bits in the OPTION register can only be set after the CODEC_MODE CODEECPDZ bit is set.

Does this make sense?

Hi,

This should not be the case. Please refer the programming sequence in the audio chapter for TPS65950.
