Logical 1 = Enable event; Logical 0 = Disable event. Refer to "Error Reporting," page 135,
for more information.
002C Built-in Test Patterns (Bars and 1kHz tone): Begins playback of an
internal NTSC or PAL color bar pattern and 1kHz audio tone. Playback continues
until a Soft Reset (0000h) command is sent.
002D Blank/Unblank Video: If bit 8 is set to 1 (Blank 012Dh), playback con-
tinues with the video blacked out (audio continues). If bit 8 is set to 0 (Unblank
002Dh), video returns to normal.
002F Volume Control: This command is implemented for compatibility with
existing SCSI decoder products; however, it is recommended that command
0008h Set Audio Gain be used instead.
0030 Enable Playback Status Return: During back-to-back playback, this
feature will return a SCSI Status Immediate Condition Met (14h) when the first
video has completed playback. Setting bit 0 = 1 of the 32-bit data enables this
feature. Bit 0 = 0 disables the feature (default at power-up). This feature re-
mains enabled until the decoder is reset or disabled by this command.
0032 Wait for Condition: This command allows the host to be notified of sever-
al decoder events. The SCSI command waits to complete until an event occurs.
The Additional Data field contains the wait condition:
0x01
0x02
Good SCSI Status is returned when this condition occurs. If the command is sent at
an inappropriate time, the following error is returned:
Illegal Request, Invalid Field Within CDB.
