Terminal Description
fe] smo [wo] we |
Output terminal for C-BUS service request.
Signal requesting for STATUS (mechanism status
information) to be sent to master when CD module
status changes.
CHusw CHUCKING SW input terminal. Terminal to detect
° completion of disc chucking
Photo sensor input terminal
Detecting the disc status incl. loading, chucking, etc..
Loading motor control terminal
When a disc is in loading or EJECT motion, these
terminals output signals by the following logic:

RESET input terminal
Terminal to input sub code synchronization to be
output from CXD2548.
C-BUS ACC CONT input terminal. If "L” is input
during disc rotation (PLAY, FF, FB, SEARCH), it
enters into power saving mode after disc rotation
stops. If “L" is input in LOADING or EJECTING, it
enters into power saving mode after completion of
motion
