Host interface connection
8.7 Interrupt
The interrupt output is a LOW level interrupt which must be connected to the interrupt
input of the DVD host.
9.
Front-end interface
First the SACD sector structure is explained and how to connect the SAA7893HL in
the different modes. For these different modes the interface timing figures will be
given.
The supported sector format interface is sketched in
Figure 34
.
