Reset input, nonmaskable interrupt input port, or bootstrap loader start (in Flash devices).
Test clock. TCK is the clock input port for device programming test and bootstrap loader start (in Flash
devices).
Test data input or test clock input. The device protection fuse is connected to TDI/TCLK.
Test data output port. TDO/TDI data output or programming data input terminal
Test mode select. TMS is used as an input port for device programming and test.
Input for an external reference voltage to the ADC
Output of positive terminal of the reference voltage in the ADC
Negative terminal for the ADC’s reference voltage for both sources, the internal reference voltage, or an
external applied reference voltage
Input port for crystal oscillator XT1. Standard or watch crystals can be connected.
Output terminal of crystal oscillator XT1
Input port for crystal oscillator XT2. Only standard crystals can be connected.
Output terminal of crystal oscillator XT2
QFN package pad connection to DVSS recommended.
