output.
SQSO readout clock input.
Sub Q P to W serial output.
SBSO readout clock input.
System reset. Reset when low.
Mute input. Muted when high.
Serial data input from CPU.
Latch input from CPU. Serial data is latched at the falling edge.
Serial data transfer clock input from CPU.
SENS output to CPU.
SENS serial data readout clock input.
Spindle motor external control input.
Digital power supply.
Digital power supply.
Anti-shock input/output.
Microcomputer extension interface (input A)
Microcomputer extension interface (input B)
Microcomputer extension interface (output)
WFCK output.
XUGF output. MINT1 or RFCK is output by switching with the command.
XPCK output. MNT0 is output by switching with the command.
GFS output. MNT3 or XROF is output by switching with the command.
C2PO output. GTOP is output by switching with the command.
Outputs a high signal when either subcode sync S0 or S1 is detected.
4.2336MHz output. In CAV-W mode, 1/4 frequency division output for VCKI.
Word clock output. f = 2Fs.
Track count signal input/output.
Mirror signal input/output.
Defect signal input/output.
Focus OK signal input/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. Or input when LKIN = 1.
Spindle motor servo control output.
Disc innermost track detection signal input.
2/3 frequency division output for XTAI pin.
