Function
XTAL2:
XTAL1:
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:
XTAL4:
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.
Reset Input with Schmitt-Trigger characteristics. A low level
at this pin while the oscillator is running resets the XC161. An
internal pullup resistor permits power-on reset using only a
capacitor connected to
A spike filter suppresses input pulses <10 ns. Input pulses
>100 ns safely pass the filter. The minimum duration for a
safe recognition should be 100 ns + 2 CPU clock cycles.
