Description
Digital power supply.
Digital GND.
Servo block internal serial data output.
Servo block internal serial data readout clock output.
Servo block internal serial data latch output.
Sub-Q 80-bit, PCM peak and level data outputs. CD TEXT data output.
SQSO readout clock input.
GRSCOR resynchronization input.
Sub 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.
Anti-shock input/output.
WFCK output.
XUGF output. MNT0 or RFCK is output by switching with the command.
XPCK output. MNT1 is output by switching with the command.
GFS output. MNT2 or XROF is output by switching with the command.
C2PO output. MNT3 or 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 and variable pitch mode, the 1/4
frequency division of V16M is output.
Word clock output f = 2Fs. GRSCOR is output by switching with the command.
Track count signal input/output.
Mirror signal input/output.
Digital GND.
Digital power supply.
Defect signal input/output.
Focus OK signal input/output.
Spindle motor external control input.
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.
