Pin Definitions and Functions

Sym- Pin Input Function

bol

Num. Outp.

RSTIN 1

I

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

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.

P20.12 2

IO

For details, please refer to the description of P20.

NMI 3

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 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.
