Notes
1. X is the read/write control bit; X = 0 is order to write (the circuit is slave receiver); X = 1 is order to read (the circuit is
2. If more than 1 byte DATA is transmitted, then auto-increment of the subaddress is performed.

PART
first field of sequence: 0 = false; 1 = first of 4 fields for NTSC (first of 8 fields for PAL). FFOS is not
valid for non-interlaced signals.
field organization: 0 = even field; 1 = odd field
lock to external chrominance: 0 = possible; 1 = not possible
sync indication: 0 = locked to external sync; 1 = external sync lost
