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.
Note: Input pin XTAL1 belongs to the core voltage domain.
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.
Note: Input pin XTAL3 belongs to the core voltage domain.
Reset Input with Schmitt-Trigger characteristics. A low-level
at this pin while the oscillator is running resets the XC161.
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.
Note: The reset duration must be sufficient to let the

It is recommended not to connect these pins to the PCB.
Therefore, input voltages must be within the range

External circuitry must guarantee low-level at the
RSTIN pin at least until both power supply voltages
have reached the operating range.
