MCU Start-up, RESET Extended Externally
8.2.2
External Reset
An External Reset is generated by a low level on the RESET pin if enabled. Reset pulses longer than the minimum pulse
width (see section “System and Reset Characteristics” on page 170) 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 – VRST – on its positive edge, the delay counter starts the MCU after the time-out period – tTOUT – has expired.
External reset is ignored during Power-on start-up count. After Power-on reset the internal reset is extended only if
RESET pin is low when the initial Power-on delay count is complete. See Figure 8-2 and Figure 8-3.
