The incoming data bus (ID[7:0]) carries
SONET/SDH frame data in byte serial format.
ID[1]
ID[2]
ID[3]
ID[4]
ID[5]
ID[6]
ID[7]
In incoming byte interface mode (IBMODE set
high), ID[7] is the most significant bit,
corresponding to bit 1 of each serial word, the
bit transmitted first. ID[0] is the least significant
bit, corresponding to bit 8 of each serial word,
the last bit transmitted. The ID[7:0] bus is
sampled on the rising edge of SCLK.
In incoming nibble interface mode (IBMODE set
low), ID[3] is the most significant bit of each
nibble, corresponding to bit 1 or bit 5 of each
serial word, the bit transmitted first and fifth,
respectively. ID[0] is the least significant bit of
each nibble, corresponding to bit 4 or bit 8 of
each serial word, the fourth or last bit
transmitted, respectively. ID[7:4] is ignored. The
ID[3:0] bus is sampled on the rising edge of
NSCLK.
