SC9636-006 Datasheet, PDF (8/12 Pages) Silan Microelectronics Joint-stock – CD DIGITAL SERVO SIGNAL PROCESSOR WITH MCU (2 DIGITS LED DISPLAY)

SC9636-006
In random mode, display track number for 5 seconds, and display circulate light for 5 seconds.
Explanation of system operation according to application circuit:
1. If the Door SW input is “close” after resetting, the system starts the CD initialization and the display
shows“- -”. If a disc is detected, the system will enter the stop mode and the display shows the total
number of tracks. If the end of the tune of final track is reached, the system will go to stop mode
and the display shows the total number of tracks.
(it can set auto play according to the AUTOP1 and AUTOP2).
2. Function Keys:
1) PLAY key: When the system is STOP mode, if the key PLAY is pressed, the track number of the
purpose will be reached and played. If the PLAY key is pressed during the CD play mode, the system
goes to the pause mode from the play mode. If the PLAY key is pressed during the CD pause mode,
the system returns to the play mode.
2) STOP key: If STOP key is pressed during the CD play mode, the system stops the disc motor, and
moves the pickup the most inside. In the stop mode, display shows the total number oh tracks.
3) NEXT key: Use to select next track or fast forward play. While the key is holding continuously over 1
second during CD play mode, the current track is playing fast forward. Otherwise the system goes to
next track.
4) PREV key: Use to reach back the tune head of the current track or select previous track of fast
backward. If the key is pressed once, the system reaches back the tune head of current track. And the
key is pressed twice in one second; the system goes to previous mode and goes to previous track.
While the key is holding continuously over 1 second during CD play mode, the current track is playing
fast backward.
5) PROG key: use to go to program mode and save any desired track up to 20 in any order.
6) REPEAT: If REPEAT key is pressed. The system changes the repeat mode cyclically from the no
repeat mode the repeat-1 mode and then to repeat-all mode.
7) Random: If Random key is pressed during the stop mode, the system searches at random and plays it.
3. Display: 2 digits LED display.
1) If a disc isn’t detected, the CD function will become ineffective and display shows” NO”.
2) Display shows“- -”during the CD initializing. (Flashing)
3) If STOP key is pressed during the CD initializing, the display shows“- -”.（no flashing）
4) The display shows “7” not “07”during playing track 8.
5) The display shows the flashing track number in pause mode.
6) When system is STOP mode, the display shows total number of tracks.
