XTAL2: Output of the oscillator amplifier circuit
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

.
V
AREF
28 – Reference voltage for the A/D converter.
V
AGND
29 – Reference ground for the A/D converter.
