Num. Outp.

RSTIN 63

I

Reset Input with Schmitt-Trigger characteristics. A low-level

at this pin while the oscillator is running resets the

XC164GM.

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

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.

NMI 64

I

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 XC164GM 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.
