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.
Shared function pin that functions either as the 16.9344 MHz output (16M) or as the C2 flag data continuity check
start signal (detection start is indicated by a low to high transition). Controlled by microcontroller commands.
