4. Operations at ACC OFF
At ACC OFF, if the system is executing the timing chart,
it completes the mode and then enters the standby
mode.
However, if a DISC IN (disc is not removed) status is
detected after completion of Eject, the system enters the
standby mode after performing the loading to protect the
disc. If a loading error occurs at that time, the system
does not shift to the eject mode but shifts after the ACC
ON.
Moreover, an OR operation is carried out for SW-A and
SW-B and the result is fed to an interruption port. If it is
"L'-+"H", the system returns from the standby mode and
carries out the loading operation.
After completion of the loading or determining the load-
ing error, the system enters the standby mode again.

7. Emergency eject process
Eject key is not accepted in all modes. However, when
ejecting in a mode other than chucking status (C mode),
the system performs the loading operation once and
then ejects as in initialization. (To prevent disc from pop-
ping out.)

8. BATT detection
When the BATT detection port detects BATT OFF, the
system enters the standby mode under any conditions.
After releasing the standby, the system checks status of
the switches and performs initialization process if the
status is other than the chucking status (C mode).
