Digital power supply.
System reset. Reset when low.
Mute input (low: off, high: on)
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. (Not connected)
XUGF output. MNT0 or RFCK is output by switching with the command. (Not connected)
XPCK output. MNT1 is output by switching with the command. (Not connected)
GFS output. MNT2 or XROF is output by switching with the command.
G2PO 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. 1/4 frequency division output for V16M in CAV-W mode or variable pitch
mode. (Not connected)
Word clock output. f = 2Fs. GRSCOR is output by the command switching. (Not connected)
