DESCRIPTION
52
O Output terminal of crystal oscillator XT2
53
I Input port for crystal oscillator XT2
58
I
Reset input, nonmaskable interrupt input port, or bootstrap loader start (in
flash devices)
57
I
Test clock (JTAG). TCK is the clock input port for device programming test
and bootstrap loader start.
55
I
Test data input or test clock input. The device protection fuse is connected
to TDI/TCLK.
54
I/O
Test data output port. TDO/TDI data output or programming data input
terminal.
56
I
Test mode select. TMS is used as an input port for device programming and
test.
10
I Input for an external reference voltage/DAC12.0 output
7
O Output of positive terminal of the reference voltage in the ADC12
11
I
Negative terminal for the reference voltage for both sources, the internal
reference voltage, or an external applied reference voltage
8
I
Input port for crystal oscillator XT1. Standard or watch crystals can be
connected.
9
O
Output port for crystal oscillator XT1. Standard or watch crystals can be
connected.
