The Message Passing mode (MSG) allows an external
device to pass raw data packets to the AMD Geode LX pro-
cessor system memory (see Figure 6-43). In Message
Passing mode, VID8 is redefined as a start message indi-
cation and VID9 is redefined as an end message indica-
tion. Video data reception (SAV/EAV packets and ancillary
packets) is disabled while in Message Passing mode.

The Data Streaming mode (STRM) allows an external
device to pass raw data to the processor system memory
(see Figure 6-44). When in Data Streaming mode, the
VID9 data pin is redefined as a DATA_VALID control input.
VID8 is the START_MSG indicator. The VIP stores all data
during the time that the DATA_VALID input is active. The
data is stored sequentially into system memory. Figure 6-
44 shows the Data Streaming format. Video data reception
(SAV/EAV packets and ancillary packets) is disabled while
in Data Streaming mode.
