TRST : JTAG Test Port Reset (Active Low)
This is the active low asynchronous reset to the JTAG Test Port. This pin has an internal pullup
resistor and it can be left disconnected.
TMS: JTAG Test Mode Select
The signal on this pin controls the JTAG test performance and is clocked into the device on rising
edges of TCK. This pin has an internal pullup resistor and it can be left disconnected.
TCK: JTAG Test Clock
This pin input the clock of the JTAG Test. The data on TDI and TMS are clocked into the device on
rising edges of TCK, while the data on TDO is clocked out of the device on falling edges of TCK.
TDO: JTAG Test Data Output
This pin output the serial data of the JTAG Test. The data on TDO is clocked out of the device on
falling edges of TCK. TDO is a Tri-state output signal. It is active only when scanning of data is
out.
TDI: JTAG Test Data Input
This pin input the serial data of the JTAG Test. The data on TDI is clocked into the device on rising
edges of TCK. This pin has an internal pullup resistor and it can be left disconnected.

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