segmentation interface, PHY mode
The segmentation-unit interface on the TNETA1575 operates as the RX UTOPIA interface on a PHY device
when the TNETA1575 is operating in PHY mode. The PHY/ATM input terminal has to be high to operate in PHY
mode.
This cell interface works on the low-to-high transition of SEGCLK to sample and generate signals. All signals
are active high, unless noted with a bar above the signal name.

reassembly interface, PHY mode
The reassembly-unit interface on the TNETA1575 functions as the TX UTOPIA interface in a PHY device when
the TNETA1575 is operating in PHY mode.
This reassembly-cell interface works on the low-to-high transition of RESCLK to sample and generate signals.
All signals are active high, unless noted with a bar above the signal name.
