CCAP
Two bytes of decoded closed caption data are available in the
I
can be obtained from the CC_EVEN_FIELD bit (Register 0x78).
CC_CLEAR, Closed Caption Clear, Address 0x78[0],
User Sub Map, Write Only, Self-Clearing
Setting CC_CLEAR to 1 reinitializes the CCAP readback
registers.
CC_AVL, Closed Caption Available, Address 0x78[0],
User Sub Map, Read Only
When CC_AVL is 0, closed captioning was not detected.
When CC_AVL is 1, closed captioning was detected.

Identifies the field from which the CCAP data was decoded.
When CC_EVEN_FIELD is 0, closed captioning was detected
from an odd field.
When CC_EVEN_FIELD is 1, closed captioning was detected
from an even field.
