RSTIN

I/O
Reset Input with Schmitt-Trigger characteristics. A low level
at this pin while the oscillator is running resets the C167CS-
3V. 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.
Note: To let the reset configuration of PORT0 settle and to
let the PLL lock a reset duration of ca. 1 ms is
recommended.
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 C167CS-3V 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.
Reference voltage for the A/D converter.
Reference ground for the A/D converter.
