JTAG Serial Data Output. This pin is the serial output for all
JTAG instruction and data registers. TDO has an internal
50 kΩ resistive pull-up to V
system if the pin is not driven.
+3.3V Supply. Positive 3.3V supply voltage for internal logic.
+3.3V, 2.5V, or 1.8V I/O Supply. Positive 3.3V, 2.5V, or 1.8V
supply voltage connected to the output voltage drivers and
input buffers.
+3.3V or 2.5V JTAG I/O Supply. Positive 3.3V or 2.5V supply
voltage connected to the TDO output voltage driver and TCK,
TMS, and TDI input buffers.
Ground
Do not connect. (These pins must be left unconnected.)
