Input Function

Outp.

RSTIN 27

I/O Reset Input with Schmitt-Trigger characteristics. A low level

at this pin while the oscillator is running resets the C164CM.

An internal pullup resistor permits power-on reset using only

a capacitor connected to VSS.

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.
