UTOPIA Transmit Cell Data Bus (TDAT[15:0]).

This data bus carries the ATM cell octets that are

written to the selected transmit FIFO. TDAT[15:0] is

considered valid only when TENB is simultaneously

asserted and the S/UNI-STAR is selected via

TADR[2:0].

TDAT[15:0] is sampled on the rising edge of

TFCLK.
