Hello,

When I use adau1777 serial output ports, I encounter some confuse problem.

When I configure I2S SAI as below.

the first channel data miss.

When I configure the LRCLK mode as Pluse, others is same with above.

the first channel data come back

And I try tdm4 TDM8. When I set LRCLK mode as 50% Duty Cycle, the first channel all miss.

Have you encounter such problem ? Is hardware or setting fault ?

Hello Brom,

Sorry it took so long to get to your issue. The serial ports do function correctly and have been fully tested so it is not a silicon issue. Can you send over your project?

It is far easier and faster to look at the project rather than asking many questions over the forum.
