Reset Input with Schmitt-Trigger characteristics. A low level
at this pin while the oscillator is running resets the XC164.
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

Non-Maskable Interrupt Input. A high to low transition at this
pin causes the CPU to vector to the NMI trap routine. When
the PWRDN (power down) instruction is executed, the NMI
pin must be low in order to force the XC164 into power down
mode. If NMI is high, when PWRDN is executed, the part will
continue to run in normal mode.
If not used, pin NMI should be pulled high externally.

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