DESCRIPTION
Positive terminal that supplies SVS, brownout, oscillator, FLL+, comparator_A, port 1, and LCD
resistive divider circuitry; must not power up prior to DVCC.
Negative terminal that supplies SVS, brownout, oscillator, FLL+, comparator_A. Needs to be externally
connected to DVSS.
Digital supply voltage, positive terminal. Supplies all parts, except those which are supplied via AVCC.
Digital supply voltage, negative terminal. Supplies all digital parts, except those which are supplied via
AVCC/AVSS.
Not internally connected. Connection to VSS recommended.
General-purpose digital I/O/Timer_A. Capture: CCI0A input, compare: Out0 output/BSL transmit
