CSND module writes state info(including state from [[CSND]] registers) for each audio channel to shared-memory for this command.
CSND module writes state info(including state from [[CSND]] registers) for each audio channel to shared-memory for this command.
=Offset1=
This section describes the structure of the data located at offset1(from [[CSND:Initialize]]) in shared-memory. This data is updated by command 0x300, and by commands which update the channel physical address registers. The following describes the format of the entries located here.

| 0 = audio channel is not playing, 1 = audio channel is playing. CSND module sets this field to zero when bit14-bit15 in the channel CNT register are all-zero, otherwise CSND module sets this to value 1.

| This is the physical address from the main physical address channel-slot register. When the audio channel is playing, this is the address of the sample-data that was being played at the time this address was written here by CSND module.
