Buffer Mode 0
The user data buffer previously described is identi-
cal for all modes. Buffer mode 0 allocates the rest
of the buffer to channel status data. This mode
stores an entire block of channel status in 24 mem-
ory locations from address 08H to 1FH. Channel
status (CS) data is different from user data in that

Audio Data
channel status data is independent for each channel.
A block of CS data is defined as one bit per frame,
not one bit per sub-frame; therefore, there are two
blocks of channel status. The CS2/CS1 bit in CR1
selects which channel is stored in the buffer. In a
typical system sending stereo data, the channel sta-
tus data for each channel would be identical.
