RF jitter amount (used to adjust the focus bias). 8-bit binary data in PER0 = LSB, PER7 = MSB.
Focus OK.
High when the frame sync and the insertion protection timing match.
GFS is sampled at 460Hz; when GFS is high, this pin outputs a high signal. If GFS is low eight consecutive samples, this pin outputs low.
High when the playback disc has emphasis.
GFS is sampled at 460Hz; when GFS is high eight consecutive samples, this pin outputs a high signal. If GFS is low eight consecutive
samples, this pin outputs low.
Used in CAV-W mode. The result obtained by measuring the rotational velocity of the disc. (See Timing Chart 2-5.) VF0 = LSB, VF9 = MSB.
