DESCRIPTION
Positive terminal that supplies SVS, brownout, oscillator, comparator_A, port 1, and LCD resistive
divider circuitry; must not power up prior to DV_CC.
Negative terminal that supplies SVS, brownout, oscillator, comparator_A. Needs to be externally
connected to DV_SS.
Digital supply voltage, positive terminal. Supplies all parts, except those which are supplied via AV_CC.
Digital supply voltage, negative terminal. Supplies all digital parts, except those which are supplied via
AV_CC/AV_SS.
Negative terminal that supplies SVS, brownout, oscillator, comparator_A. Needs to be externally
connected to DV_SS.
Not internally connected. Connection to V_SS recommended.
