Causes if with a DVD
A command could not be issued to DSP because
Command Busy (XCBUSY) was in force
(XCBUSY = L) for a specified time (about 200
µS).
Command Busy (XCBUSY) was in force for a
specified time (about 200 µS) before and after a
coefficient read command was issued to DSP, or
the address echo-back after command issuance
did not match the setup address.
Command Busy (XCBUSY) was in force for 200
µS during continuous coefficient writing, or before
and after a continuous write command was
issued to DSP.
In the backup sequence, codes could not be read for fixed time.
Cannot close tracking even if performs backup fixed number of times.
During tracing, do not restore after the runaway detection backup was performed
several times.
During playback, the overcurrent detection port was at L for 300 ms or more
continuously.
After the overcurrent detection (C3 error), furthermore the overcurrent detection port
was at L for 300 mS or more continuously.
The tray switch that had been Open mode was forcibly changed to a mode other
than Open by an external force.
Loading or unloading could not be completed
within a specified time (about 10 seconds).
Though a portable cover is opening, when a
