6.9 DVD Serial Data Interface
This interface connects to the data port of low cost
DVD loaders using a 4-wire serial interface. In this
case, control for the loader will typically be done
using the 2-wire serial interface master. The ATA-
PI/IO channel pins are then free to be used for a
second DVD loader, a general purpose ATAPI, or
as GPIOs.
