Focus drive output.
Digital power supply.
Track count signal output.
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.
Spindle motor servo control output.
Spindle motor servo control output.
Disc innermost track detection signal input.
2/3-frequency division output for Pins 103 and 104.
Digital servo reference clock input.
Crystal selection input. Low when the crystal is 16.9344MHz; high when the
crystal is 33.8688MHz.
4.2336MHz output.
D/A interface. Word clock f = 2Fs
Digital power supply.
D/A interface. LR clock f = Fs
