Pin Name
Digital out output pin.
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, but only the controller
power supply can be set to on, enabling 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.
Inverted input pin for low-pass filter amp.
Output pin for low-pass filter amp.
