It seems to just set the system clock + division parameters. I might have a go sometime to just try some things and see what happens. If only we could monitor what the actual clock frequency is (+ I/O bus too), now I don't see another way than counting cycles of a busy loop against a "wall" clock.
Yeah it seems to be used for SPI, or at least the SLC stuff - the one thing it doesn't seem to ever be used for right now is i2c!!! LOL
I wonder if we can set the divisors to various values, measure the i2s bit clock and deduce it from there?
