Description
Ancillary Packet Interrupt Threshold Value. This value determines when the ancillary
interrupt occurs. The Ancillary Packet Count (APC) bits (VIP Memory Offset 08h[31:24])
is compared to this value. If the APC is equal to or greater then this value, the ancillary
interrupt is generated.
Reserved.
Ancillary Data/Message Passing Data/Data Streaming Buffer Size. This register
specifies the size of the ancillary, message passing, and data streaming buffers in bytes.
Changes to this register take effect immediately (not double buffered). The value in this
register is 8-byte aligned. Bits [2:0] are ignored.
Description
Page Offset. This register specifies the offset to the next page of buffer data. If the page
count is 2 or greater, the next frame of data is started at an address of buffer +
PAGE_OFFSET. Up to eight pages (frames) can be accumulated. The address of the
next frame is located at a “Page Offset” address. Note that ancillary data and MSG/
STRM data is not paged. This only applies to video and VBI data. The value in this regis-
ter needs to be 32-byte aligned. (Bits [4:0] are required to be 00000.)
