Figure 23. MCU Start-up, RESET Extended Externally
An External Reset is generated by a low level on the RESET pin. Reset pulses longer
than the minimum pulse width (see Table 18) 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
counter starts the MCU after the Time-out period t
