I Reset: A high on this pin for two machine cycles while the oscillator is running,

resets the device. An internal diffused resistor to VSS permits a power-on reset

using only an external capacitor to VCC. If the hardware watchdog reaches its

time-out, the reset pin becomes an output during the time the internal reset is

activated.
