voltage invokes the delay counter, which determines how long the device is kept in RESET after
V
CC rise. The RESET signal is activated again, without any delay, when VCC decreases below
the detection level.
Figure 9-2.
MCU start-up, RESET tied to V
CC.
Figure 9-3.
MCU start-up, RESET extended externally.
Note:
If VPOR or VCCRR parameter range can not be followed, an external reset is required.

External reset
An External Reset is generated by a low level on the RESET pin. Reset pulses longer than the
minimum pulse width (see Table 9-1 on page 58) will generate a reset, even if the clock is not
running. Shorter pulses are not guaranteed to generate a reset. When the applied signal
reaches the Reset Threshold Voltage – V
RST – on its positive edge, the delay counter starts the
MCU after the Time-out period – t
TOUT – has expired.
