LRCLK_OUT2\MP8 routing

Hello Insane,

From the name of the pin I assume you are using an ADAU1452?

It is not possible to route the clicks from the input ports over to the output ports.

You cannot use the GPIO because that goes through the code and so it is updated at the core sampling rate. Too slow for bitclock.

What do you mean when you say "I need to see the input clocking"?

I think there may be another way to do this. I am assuming you want to know what the sampling rate is on the serial input port?

Route the serial input port over to an ASRC. Then set the output of the ASRC to the core sampling rate. Then poll the ASRC Ratio Registers and it will tell you the ratio as compared to the core sampling rate. These are at addresses 0xF582 to 0xF589.

Explain more what you need to do and I might have a project that I have previously prepared to solve the problem.
