DESCRIPTION
VER − version identification of the device: it will be changed with all versions of the IC that have
different programming models; current version is 101 binary
CCRDO 1 Closed Caption bytes of the odd field have been encoded
0 the bit is reset after information has been written to the subaddresses 67H and 68H; it is
set immediately after the data has been encoded
CCRDE 1 Closed Caption bytes of the even field have been encoded
0 the bit is reset after information has been written to the subaddresses 69H and 6AH; it is
set immediately after the data has been encoded
FSEQ 1 during first field of a sequence (repetition rate: NTSC = 4 fields, PAL = 8 fields)
0 not first field of a sequence
O_E 1 during even field
0 during odd field
DATA BYTE DESCRIPTION
CID chip ID of SAA7104E = 04H; chip ID of SAA7105E = 05H

DESCRIPTION
IFERR 0 normal FIFO state
1 input FIFO overflow/underflow has occurred
BFERR 0 normal FIFO state
1 buffer FIFO overflow, only if YUPSC = 1
OVFL 0 no FIFO overflow
1 FIFO overflow has occurred; this bit is reset after this subaddress has been read
UDFL 0 no FIFO underflow
1 FIFO underflow has occurred; this bit is reset after this subaddress has been read
