RESET
The RESET pin (active LOW input) is used to initialize the
microcontroller to a defined state. The Reset configuration
is shown in Fig.5.

Power-on-reset
The Power-on-reset circuit monitors the voltage level of
VDD. If VDD remains below the internal reference voltage
level Vref (typically 1.3 V), the oscillator is inhibited.
When VDD rises above Vref, the oscillator is released and
the internal reset is active for a period of td (typically
50
µs).
Considering the VDD rise time, the following measures for
a correct Power-on-reset can be taken:
• If the VDD rises above the minimum operation voltage
before time period td is exceeded, no external
components are necessary (see Fig.6).
• If V
DD has a slow rise time, such that after the time
period (tVref +td) has elapsed the supply voltage is still
below the minimum operation voltage (Vmin),
external components are required (see Figs 4 and 7).
To guarantee a correct reset operation, ensure that the
time constant RC
≥ 8 × tVDD.
A definite Power-on-reset can be realized by applying an
(external) RESET signal during power-on.
