SBOK
Subcode Q data CRCC determination result output pin. It
outputs a high when CRCC check is found OK.

V
SS
CD unit's digital block power supply pins.
Normally, apply 5 V to V
DD
.
When not using a CD (CD off), this power supply can be
turned off, with only the controller power supply kept
active, so that the controller alone is operating. In this
case, the CDoff bit must be set to 1. When this bit is set to
1, pins 11 through 18 and pins 39 through 42 all are
changed for output ports if they have been set for CD
control signal input/output pins.
