DAC3 Voltage Output on ADuC7020. On the ADuC7019, a 10 nF capacitor
must be connected between this pin and AGND/Single-Ended or
Differential Analog Input 15 (see Figure 43).
Test Mode Select, JTAG Test Port Input. Debug and download access.
This pin has an internal pull-up resistor to IOV
pull-up resistor (~100K) is also required to ensure that the part does not
enter an erroneous state.
