TDO: JTAG Test Data Output
The serial data of the JTAG test is output on this pin. The data on TDO pin is clocked out of the device on
the falling edges of TCK. TDO is a high impedance output signal. It is active only when scanning of data is
over. This pin should be left float when unused.

TDI: JTAG Test Data Input
The serial data of the JTAG test is input on this pin. The data on TDI pin is clocked into the device on the
rising edges of TCK. This pin has an internal pull-up resistor and it can be left disconnected.

3.3 V/5 V Power Supply for Transmitter Driver
All VDDT pins must be connected to 3.3 V or all VDDT must be connected to 5 V. It is not allowed to leave
any of the VDDT pins open (not-connected) even if the channel is not used.
T1 is only 5V VDDT.
