Status Read Timing
Table below shows the contents of each data output when reading the status of the channels.
The BUSY signal outputs “L” level when either a command is being processed or the playback of a pertinent
channel is going on. In other states, the BUSY signal outputs “H” level.
The NCR signal outputs “L” level when either a command is being processed or a pertinent channel is in standby
for playback. In other states, the NCR signal outputs “H” level.
