This active-low signal is used to initialize the JTAG logic
asynchronously.
Used to synchronize the JTAG logic.
Used to sequence the JTAG state machine. TMS is sampled on the
rising edge of TCLK.
Inputs to the A-to-D converter.
Reference voltage high and low inputs.
Isolate the ADC circuitry from power supply noise
