I Reset input, nonmaskable interrupt input port, or bootstrap loader start (in Flash devices).
I Test clock. TCK is the clock input port for device programming test and bootstrap loader start
I Test data input or test clock input. The device protection fuse is connected to TDI/TCLK.
I/O Test data output port. TDO/TDI data output or programming data input terminal
I Test mode select. TMS is used as an input port for device programming and test.
I Input for an external reference voltage
O Output of positive terminal of the reference voltage in the ADC12
I Negative terminal for the reference voltage for both sources, the internal reference voltage, or an external
applied reference voltage
I Input port for crystal oscillator XT1. Standard or watch crystals can be connected.
O Output terminal of crystal oscillator XT1
I Input port for crystal oscillator XT2. Only standard crystals can be connected.
O Output terminal of crystal oscillator XT2
NA QFN package pad connection to DV_SS recommended (RTD package only)
