16) STOP MARKER

LD/CD

Function:

Stop marker is set to the specified address.

Format:

Address

S M

Explanation: The specified address is written in the Mark Frame/Time/Block Register or Mark Chapter/Track Register as indicated by the address flag, and the completion status “R” is returned immediately. When the stop marker address is reached in Play or Multi-Speed Mode with a CAV Disc, Still Mode occurs. When the stop marker address is reached in Play with a CLV disc Pause Mode occurs. In both cases, when the stop marker address is reached, the stop marker is cleared from the mark register. The stop marker is also cleared when a step command is issued to step through the address marker an a CAV disc.

Here, the completion status “R” is returned when the command is received and the stop marker is set, not when the address marker is reached, as described in the Play command. Issue a disc location request command (?F,?C,?T,?R etc.) to determine whether not the stop marker address has been reached. If a Clear or Reject command is sent before the stop marker is reached, the stop marker in the the mark register is cleared.

The stop marker is functionally similar to the auto stop operation of the Play and the Multi-Speed commands. However, the auto stop and the stop marker return a completion status at different times. In an auto stop operation, the completion status is returned when the marked address is reached. In the stop marker operation, the completion status is returned when the stop marker is set. The stop marker command must be used when status requests are sent to the player before the address marker is reached; it is also useful when the operation mode is changed before the marked address is reached.
