long data formats on DMA.
Supports block transfers for graphics bit blits.
MPEG VIDEO DECODER
Supports VCD1.0, 1.1, 2.0 and 3.0, SVCD, and
DVD video standards.
Supports trick features, including smooth 2x
forward play.
Special anti-tearing logic controls picture de-
code and presentation.
Advanced error concealment hardware.
SYSTEM SYNCHRONIZATION
System time clock (STC) for audio/video syn-
chronization
Flexible interrupt structure for controlling de-
code and presentation times
Hardware scheduling of sub-picture and high-
light events
AUDIO INTERFACE
Supports 8 channels PCM, I
and 96 kHz output rate.
Simultaneous IEC-958 output with program-
mable channel status and user data
Also supports S/PDIF receiver for high perfor-
mance applications
EXTERNAL INTERFACE
2-wire serial master and slave port, second 2-
wire master port for controlling DVD device.
3- or 4-wire serial master/slave port.
Large number of programmable bi-directional
I/O pins.
All pins not used for other function can be reas-
signed as general purpose I/O pins
8 pins can be used as edge or level detection in-
terrupt pins.
Hardware-assisted support for infrared remote
devices, such as remote control, infrared key-
board, mouse, printer, and more.
Programmable parallel host master interface
supports formats including ATAPI, ISA, and
more.
