one register.
2 8-level by 8-bit FIFO are used to buffer data for TX and RX. After received 192 frame- four bytes of
channel status was appended into the RX FIFO. When TX FIFO is empty and SPDIF is enabled, 0 is send out
for all frame.
The AES/EBU interface is a means for serially communicating digital audio data through one
single transmission line. It provides two channels for audio data, a method for
communicating control information, and has error detection capabilities. The control
information is transmitted as one bit per sample and accumulates in a block structure. The
data is bi-phase encoded, which enables the receiver to extract a clock from the data .
Coding violations, defined as preambles, are used to identify sample and block boundaries.
