Pin Name
Digital output in.
Sub code block sync output pin.
When sub code sync is detected, outputs
High at the S1 position.
Sub code Q data CRCC result output pin.
When the result is OK, outputs High.
Power supply pins for CD digital block.
Normally, 5 V is applied.
When CD is not used (CD off), the power
supply can be set to off except to the
controller, enabling only the controller to
operate. At this time, 1 must be set in the
CDoff bit. If pins from 11 to 18 and 39 to 42
are set as CD control signal input/output pins,
setting the CDoff bit to 1 switches all the pins
to an output port.
2V
Outputs phase error signal between the EFM
and PLCK signals.
TMAX detection result output pin. Selected by
command bit TMPS.
Longer than the specified cycle: Outputs
P2V
Shorter than the specified cycle: Outputs Low
