Applications
* since most µP and other circuitry is inoperative with VCC below 1.0V. However, in applications where RESET must be valid down to 0V, adding a pull down resistor to RESET causes any stray leakage currents to flow to ground, holding RESET low. R1’s value is not critical; 100k is large enough not to lo
