General I/O pin 3. This controls the commands from the microcontroller. This pin is shared exclusively with
the subcode read clock input (SBCK). When not used, either set this as an input port and connect to 0 V, or set
this as an output port and leave it open.
General I/O pin 4. This controls the commands from the microcontroller. This pin is shared exclusively with
the subcode frame sync signal output (SFSY). When not used, either set this as an input port and connect to 0
V, or set this as an output port and leave it open.
General I/O pin 5. This controls the commands from the microcontroller. This pin is shared, exclusively, with
the subcode P, Q, R, S, T, U, V, W output (PW). When not used, either set this as an input port and connect to
0 V, or set this as an output port and leave it open.
Subcode block sync signal output.
Test input. Equipped with an internal pull-down resistor. Must be connected to 0 V.
Digital output. EIAJ format.
Test input. Equipped with an internal pull-down resistor. Must be connected to 0 V.
16.9344 MHz output.
4.2336 MHz output.
C1, C2, one error, two error error correction monitor output
7.35 kHz sync signal output (frequency divided from the crystal oscillator).
Deemphasis monitor output. When high level, a deemphasis disk is being played back.
C2 flag output.
Test output. Under normal operation, this should be left open.
DRAM switch: high : 1M, low : 4M
Test input. Must be connected to 0V.
Test input. Must be connected to 0V.
For the one-bit D/A
converter
Crystal oscillator power supply.
16.9344 MHz crystal oscillator connection.
Crystal oscillator ground. Must be connected to 0 V.
Read/write control input. Schmidt input.
Microcontroller command input.
Input pin for the command input latch clock and the subcode readout clock. Schmitt input.
Subcode Q output.
Subcode Q output standby output.
Operating mode switch: high: shock proof, low: through.
DRAM empty (an RZP pulse is output when the DRAM is empty).
External reset input: low reset (all internal blocks are reinitialized).
L channel mute output.
L channel power supply.
L channel output.
L/R channel ground. Must be connected to 0 V.
R channel output.
R channel power supply.
R channel mute output.
