XTAL2 61
O
XTAL2: Output of the oscillator amplifier circuit
XTAL1 60
I
XTAL1: Input to the oscillator amplifier and input to the
internal clock generator
To clock the device from an external source, drive XTAL1,
while leaving XTAL2 unconnected. Minimum and maximum
high/low and rise/fall times specified in the AC Characteristics
must be observed.

Note: Input pin XTAL1 belongs to the core voltage domain.
Therefore, input voltages must be within the range
defined for V_DDI.
Reference voltage for the A/D converter
Reference ground for the A/D converter
Digital Core Supply Voltage (On-Chip Modules):

Connect decoupling capacitors to adjacent V_DD/V_SS pin pairs
as close as possible to the pins.
All V_SS pins must be connected to the ground-line or ground-
plane.
