I/O General-purpose digital I/O pin
I/O General-purpose digital I/O pin
I/O General-purpose digital I/O pin
I/O General-purpose digital I/O pin
I/O General-purpose digital I/O pin
O General-purpose digital I/O pin/Output terminal of crystal oscillator XT2
I
General-purpose digital I/O pin/Input port for crystal oscillator XT2. Only standard
crystals can be connected.
O Output terminal of crystal oscillator XT2
I Input port for crystal oscillator XT2
I
Reset input, nonmaskable interrupt input port, or bootstrap loader start (in flash
devices).
I
Test clock (JTAG). 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/DAC12.0 output
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 port for crystal oscillator XT1. Standard or watch crystals can be connected.
NA Reserved pins. Connection to D/AV_SS recommended.
