Function

RSTIN

63

I

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

this pin while the oscillator is running resets the XC164CM.

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 XC164CM 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.

Port 9 is a 6-bit bidirectional I/O port. Each pin can be

programmed for input (output driver in high-impedance state)

or output (configurable as push/pull or open drain driver). The

input threshold of Port 9 is selectable (standard or special).
