To start Ancillary Data Extraction, the ANC_DATA_EXT_MASK bit of the host interface

must be set LOW. Ancillary data packet extraction begins in the following frame (see

Figure 4-30: Ancillary Data Extraction - Step A).

Figure 4-30: Ancillary Data Extraction - Step A

Ancillary data is written into Bank A until full. The Y/1ANC and C/2ANC output flags

can be used to determine the length of the ancillary data extracted and when to begin

reading the extracted data from memory.

While the ANC_DATA_EXT_MASK bit is set LOW, the ANC_DATA_SWITCH bit can be

set HIGH during or after reading the extracted data. New data is then written into Bank

B (up to 1024 x 16-bit words), at the corresponding host interface addresses (see Figure

4-31: Ancillary Data Extraction - Step B).
