XTAL2 137 O
XTAL1 138 I
XTAL2: Output of the main oscillator amplifier circuit
XTAL1: Input to the main 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.
XTAL3 140 I
XTAL4 141 O
XTAL3: Input to the auxiliary (32-kHz) oscillator amplifier
XTAL4: Output of the auxiliary (32-kHz) oscillator
amplifier circuit
To clock the device from an external source, drive XTAL3,
while leaving XTAL4 unconnected. Minimum and maximum
high/low and rise/fall times specified in the AC
Characteristics must be observed.
