Crystal oscillation circuit input. When the master clock is input externally, input it
from this pin.
Crystal oscillation circuit output.
Connect ground.
Control the spindle motor (during focusing and jumping, if MOT_CTRL output high
level signal, it can control the MOT control port of SA9529 after through 3 voltage
drop diodes, then prevent the spindle reverse; in other condition, the MOT-CTRL
output low level).
D/A interface. LR clock output.
