About AP1_OUT of ADV7625


Please tell me about ADV7625.

I set the AP1_OUT port pins individually using the tristate_ap1_out_x [7:0] control register.

I'd like to use the AP1_OUT4 port, but the port couldn't communicate as I2S data.

The AP1_OUT port 0 and 1 were working as I2S data and I could measure their waveform.

Could you help me?

Best Regards

  • Hi,

      As stated in previous comment, Are you configuring register " i2s_spdif_map_rot=00 & i2s_spdif_map_inv =1" ?

      Please let us know, whether you are using one of our Eval board ?

      Note: i2s_spdif_map_rot[1:0] - This control is used to select the arrangement of the I2S/SPDIF interface on the corresponding APx_OUT audio output port pins and the arrangement of the I2S/SPDIF interface on the audio output port pins is determined by "I2S_SPDIF_MAP_ROT".
