This input pin is used to insert externally
supplied framer Opportunity bits into
transmitted bit stream.
Used to indicate to the system when to
insert new Opportunity bits on the TEXTI
pin.
This pin is internally pulled low.
MODE: CDBypass = 0
Not used.
MODE: CDBypass = 1
Serial data input to the framer
transmitter controlled by TxTimSel[1:0]
bits in the corresponding port Mode
Control register, PORTn. TxDATI is
sampled on the falling edge of one of the
following clock sources: REFCKI,
TxCKI[11:0], RxCKI[11:0], or
RxCKI[11:0].
This pin is internally pulled low.
If selected as the transmitter clock
source, it is used to clock transmit data
from the cell delineator to the framer or
from the TxDATI pin to the framer. The
data inputs are sampled on the falling
edge.
Schmitt trigger input.
