Reset Input with Schmitt-Trigger characteristics. A low
level at this pin while the oscillator is running resets the
C161PI. An internal pullup resistor permits power-on
reset using only a capacitor connected to
9
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
C161PI 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.
