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.

command processing. After the command processing is completed, D7-D0 pins output ”H” level.
