Cell Transmit Data Transfer Register
Octet(4n+2)(7:0) Payload data Octet (4n+2)
Octet(4n+3)(7:0) Payload data Octet (4n+3)
The payload data octets of a cell to be inserted in either upstream
or downstream direction are written by consecutive write accesses
to registers UTXDAT0/DTXDAT0 and UTXDAT1/DTXDAT1 in
alternating manner until end of packet:
cycle n=0: Octet 0 and 1: write to UTXDAT0/DTXDAT0
cycle n=0: Octet 2 and 3: write to UTXDAT1/DTXDAT1
cycle n=1: Octet 4 and 5: write to UTXDAT0/DTXDAT0
cycle n=1: Octet 6 and 7: write to UTXDAT1/DTXDAT1
