Figure 27. MCU Start-up, RESET Controlled Externally
An External Reset is generated by a low level on the RESET pin. Reset pulses longer than 500
ns 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
positive edge, the delay timer starts the MCU after the Time-out period t
