ADV7180 Xtal frequency

In the ADV7180 RevF manual, in reg 0x1D ADI_Control2, bit 6 is EN28XTAL:

0 = Use 27 MHz crystal

1 = Use 28 MHz crystal

This bit is not described further in the document. What are the effects of using a 27 MHz crystal instead of the 28.6363 MHz crystal? I think that auto detection of input format will be affected.
