5.3.2 External Reset
An external reset is generated by applying a logic 0 for 1 1/2 tcyc to the
RESET pin. A Schmitt trigger senses the logic level at the RESET pin.
A COP reset or an illegal address reset pulls the RESET pin low for one
internal clock cycle. A low-voltage reset pulls the RESET pin low for as
long as the low-voltage condition exists.
NOTE:
To avoid overloading some power supply designs, do not connect the
RESET pin directly to VDD. Use a pullup resistor of 10 k or more.
