Set shield time of the motor error signal (the initial value is 40H), the
parameter is 00H~FFH, the internal reference is 8ms, so the shield time is
0~2 seconds; if the motor rotate speed is detected in the set range, and
detect the shield time of motor error signal is exceed, the system consider
the servo is abnormally and need restart.
Start play, if not read TOC, then store the TOC data; when play at the
export section, if the sub-controller at normal play state, the system will
receive the command of master controller.
read and save TOC information again, and stay in the lay in section.
Pause.
Fast play, at this time, playing at FAST_STEP, and FAST_TIME interval,
after fast forward to export section, it entry pause mode, wait for the next
command.
Fast backward, playing at FAST_STEP, and FAST_TIME interval. After
fast backward to import section, it enter pause mode and wait for the
command of master controller.
Stop play, and switch bare head to inside track.
If it is in the lay in section, then jump out the lay in section, and play at the
target track.
The target track set command: 0X11
If it is in the lay in section, then jump out the lay in section, and play at the
target track.
The target track set command: 0X12, 0X13, 0X14
If it is in the lay in section, then jump out the lay in section, and play at the
relative time of target track.
Set command: 0X11, 0X12, 0X13, 0X14

Jump to the next session; if there are a next session, then store the start
address of program to the NEXT_AMIN, NEXT_ASEC, NEXT_AFRM; If
there are no next session, then the NEXT_AMIN, NEXT_ASEC,
NEXT_AFRM remain original value or is 0XFF.
Stop at the former play point, the sled motor will not return.
This command used for control sled motor in or out after servo stop:
5FH + 81H, 0FH + 21H
5FH + 7FH, 0FH + 21H Sled motor sled outside.
5FH + 00H, 0FH + 21H Sled motor stop.
