Figure 3-12: Ancillary Data Extraction and Reading
%%
ANC_DATA_SWITCH = HIGH
ANC_DATA_SWITCH bit is toggled HIGH. New ancillary data is written
to second half of FIFO starting at adress zero. Application layer continues to
read from the first half of the FIFO.

ANC_DATA_SWITCH bit is toggled HIGH. New ancillary data is written to first half of
FIFO starting at address zero. Application layer continues to read from second half
of FIFO. Toggling ANC_DATA_SWITCH back LOW will clear the second half of the
FIFO and go back the situation depicted in box A.

NOTE: At least 1100 PCLK cycles must pass between toggles of the ANC_DATA_SWITCH bit.
The bit must be toggled at a point where no extraction is occuring (i.e. the ANC signal is LOW).
