Latency in Sigma DSP


Hi Team!

I have a doubt regarding how much is the system latency in ADAU1452/ADAU1467 .This is not to be confused with the processor latency which could be the time it takes for data to traverse  from input to output (lets say we call that processing latency) but if i were at all to peruse the latency that is a sheer contribution from the system (be it the interrupt initialization or things that are automatically taken care of either at run time or compile time )

How can one find out the total overall latency (system +processing ) and what would be a feasible way to do this ???

I understand that this would vary since different projects could involve different latency values at the systems end ..

Would appreciate if this could be calculated and shown with the simplest example project below
