87
I/O
General-purpose digital I/O / Timer_A. Capture: CCI0A input,
compare: Out0 output
88 O Output terminal of crystal oscillator XT2
Input port for crystal oscillator XT2. Only standard crystals can be
89
I _connected.
90
I/O
Test data output port. TDO/TDI data output or programming data input
terminal

Negative terminal that supplies SVS, brownout, oscillator, FLL+,
comparator_A, port 1, and LCD resistive divider circuitry.
99
Digital supply voltage, negative terminal. Supplies all digital parts,
except those which are supplied via AVCC/AVSS.
Positive terminal that supplies SVS, brownout, oscillator, FLL+,
100
comparator_A, port 1, and LCD resistive divider circuitry; must not
power up prior to DVCC1/DVCC2.
