Not natively... you may be able to make it work by bitbanging or by some smart abuse of the SPI or I2S peripheral though. That would need a fairly deep dive into the hardware, however.

...because it makes no sense to implement special protocol handling hardware for an obsolete protocol into a modern-age microcontroller? Again, not saying you can't make it work with the existing peripherals somehow, though.
