Power-on reset
When VDD is turned on, and provided its rise-time does not
exceed 10 ms, an automatic reset can be obtained by
connecting the RST pin to VDD via a 2.2 F capacitor.
When the power is switched on, the voltage on the RST pin
is equal to VDD minus the capacitor voltage, and
decreases from VDD as the capacitor charges through the
internal resistor (RRST) to ground. The larger the capacitor,
the more slowly VRST decreases. VRST must remain above
the lower threshold of the Schmitt trigger long enough to
effect a complete reset. The time required is the oscillator
start-up time, plus 2 machine cycles, or 16 x 2048 cycles
of the on-chip watchdog oscillator if it is running, whichever
is longer (see Fig.25).
