When asserted, the internal boundary-scan logic is reset. This pin
has a pull-up resistor.
Samples the value of TMS and TDI on its rising edge to control the
boundary scan operations.
Controls the boundary-scan Test Access Port (TAP) controller
operation. This pin has a pull-up resistor.
The serial test data input. This pin has a pull-up resistor.
The serial test data output.
Factory test use only, tie to VSS.
Factory test use only, tie to VSS.
When this pin is high, all outputs are tristate.
If this pin is tied low, the PHY UTOPIA Interface mode is selected.
If this pin is tied high, the PHY Serial mode is selected (as shown
in this table).
Most of the IMA logic circuits use this clock (or a derivative of it).
It can also be used as a T1/E1 reference clock. Refer to
Section
If Ref_Xclk is to be used as a reference clock, set the frequency as
shown in
Transmit Reference Clocks.
