DALLAS, TEXAS 75265
USERDATA [17:0], user-data registers, 7:0 (2600-2611h)
This 18 bytes of user data is byte accessible in random order. When in fast mode, the first 18 bytes of user data
associated with each I-frame is extracted and stored for the host to read out. A user-data interrupt is generated
(when enabled). Stored data is overwritten when new user data is found and, if INT is low (previous interrupt
not serviced), it remains low.
VERSION, device-version register, 7:0 (2427h)
Contains the version number of the ’AV220. This is a read-only register.
VID_STRM_ID, video-stream ID select (242Ah)
This register sets the video-stream ID to decode. The MPEG-1 specification allows for 16 different video-stream
IDs, all of which are supported with the ’AV220. The default is video-stream ID zero. In still-mode, the ’AV220
decodes streams with ID = 1 or the value of VID_STRM_ID is decoded by the ’AV220 video decoder.
