Tri-State Control. Set high to tri-state all outputs and I/O pins
(including the parallel control port). Set low for normal operation.
Useful in board-level testing.
Transmit Negative Data. Sampled on the falling edge (CES = 0) or
the rising edge (CES = 1) of TCLK for data to be transmitted out
onto the line.
Transmit Power-Down
0 = normal transmitter operation
1 = powers down the transmitter and tri-states the TTIP and TRING
pins
Transmit Positive Data. Sampled on the falling edge (CES = 0) or
the rising edge (CES = 1) of TCLK for data to be transmitted out
onto the line.
Transmit Tip and Ring [TTIP and TRING]. Analog line driver
outputs. These pins connect via a step-up transformer to the line.
See Section
Transmit Data Source Select Bits 0 and 1 [H/W Mode]. These
inputs determine the source of the transmit data. See
Positive Supply. 3.3V ±5%
Voltage Supply Mode. Should be tied low for 3.3V operation.
