CLK2 is input
CLK2 is output (only if DCO-X is active)
CLK1 is input
CLK1 is output (only if DCO-R is active)
Port XMFS is active low.
Port XMFS is active high.
A 1.544/6.176MHz clock has to be sourced by the system if
the internal generated transmit clock (DCO-X) is not used.
Optionally this input is used as a synchronization clock for the
DCO-X circuitry with a frequency of 1.544 or 6.176 MHz.
Marks the beginning of every transmit multiframe.
Marks the time slots which are defined by register TTR(4:1) of
every frame on port XDI.
Marks the S
Frequency: 1.544MHz
With a high level on this port the transmit lines XL1/2 or
XDOP/N are set directly into tristate. This pin function is
logically ored with register XPM2.XLT.
