The data input bus (DIN[7:0]) carries
SONET/SDH frame data in byte serial format.
DIN[7] is the most significant bit, corresponding
to bit 1 of each serial word, the bit transmitted
first. DIN[0] is the least significant bit,
corresponding to bit 8 of each serial word, the
last bit transmitted. The DIN[7:0] bus is sampled
on the rising edge of SCLK.

110 The data output bus (DOUT[7:0]) carries
SONET/SDH frame data in byte serial format.
DOUT[7] is the most significant bit,

corresponding to bit 1 of each serial word, the bit
transmitted first DOUT[0] is the least significant
bit, corresponding to bit 8 of each serial word,
the last bit transmitted. DOUT[7:0] contains valid
data only for bytes in the AU3 or AU4 virtual
container(s), or the STS-1 synchronous payload
envelopes. Its contents should be ignored for
bytes in the transport overhead. The DOUT[7:0]
bus is updated on the rising edge of SCLK.

OPAR
Output
89
The outgoing stream parity (OPAR) signal carries
the parity of the outgoing data stream. Odd
parity is selected by setting the OOP register bit
in the master parity configuration register high,
and even parity is selected by setting the OOP
bit low. OPAR is updated on the rising of SCLK.
