XTAL2:
XTAL1:
Output of the oscillator amplifier circuit.
Input to the oscillator amplifier and input to
the internal clock generator
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.
Reset Input with Schmitt-Trigger characteristics. A low level
at this pin while the oscillator is running resets the C164CI.
An internal pullup resistor permits power-on reset using only
a capacitor connected to
V
SS
.
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.
In bidirectional reset mode (enabled by setting bit BDRSTEN
in register SYSCON) the RSTIN line is internally pulled low
for the duration of the internal reset sequence upon any reset
(HW, SW, WDT). See note below this table.
Internal Reset Indication Output. This pin is set to a low level
when the part is executing either a hardware-, a software- or
a watchdog timer reset. RSTOUT remains low until the EINIT
(end of initialization) instruction is executed.
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 C164CI to go 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.
