VCC
VCC - +5V. Processor power supply.
1, 25
18, 46
GND
GND - Processor digital circuit ground.
29
22
VCC2
VCC2 - +5V Real Time Clock supply. VCC2 is isolated from VCC to
isolate the RTC from digital noise.
26
19
GND2
GND2 - Real Time Clock circuit ground.
12
5
RST
RST - Input. This pin contains a Schmitt voltage input to
recognize external active high Reset inputs. The pin also employs
an internal pulldown resistor to allow for a combination of wired
OR external Reset sources. An RC is not required for power-up, as
the device provides this function internally.

XTAL2
XTAL1
XTAL1, XTAL2 - The crystal oscillator pins provide support for
parallel resonant, AT cut crystals. XTAL1 acts also as an input if
there is an external clock source in place of a crystal. XTAL2 is
the output of the crystal amplifier.
