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

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.
