Transmit Cell Data Bus (TDAT[15:0]). This
bus carries the ATM cell octets that are
written to the selected transmit FIFO.
TDAT[15:0] is sampled on the rising edge
of TFCLK and is considered valid only
when TENB is simultaneously asserted
and the S/UNI-QJET has been selected
via the TADR[4:2] and PHY_ADR[2:0]
inputs.
The S/UNI-QJET can be configured to
operate with an 8-bit wide or 16-bit wide
ATM data interface via the ATM8 input pin.
When configured for the 8-bit wide
interface, TDAT[15:8] are not used and
should be tied to ground.
