TDLSIG/
I/O
Transmit Data Link Signal (TDLSIG).
The TDLSIG signal is input on this pin
when the internal HDLC transmitter
(XFDL) is disabled from use. TDLSIG
is the source for the data stream to be
inserted into the selected data link
bits. The E1XC may be configured to
utilize timeslot 16 as a data link or
utilize any combination of the national
bits as a data link. TDLSIG is
sampled on the rising edge of
TDLCLK.
TDLINT
Transmit Data Link Interrupt (TDLINT).
The TDLINT signal is output on this
pin when XFDL is enabled. TDLINT
goes high when the last data byte
written to the XFDL has been set up
for transmission and processor
intervention is required to either write
control information to end the
message, or to provide more data.
