Function and Operation
Remarks
43
DOUT
Digital output in.
44
SBSY
Sub code block sync output pin.
When sub code sync is detected, outputs
High at the S1 position.
45
SBOK
Sub code Q data CRCC result output pin.
When the result is OK, outputs High.
46, 75

47, 76
V
SS
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.
