When power is supplied to MICOM, reset circuit

initializes RAM and other parts on MICOM to

initialize all programs. Reset voltage maintains “low”

for hundreds of µsec comparing to MICOM Vcc

voltage when power is input. It also maintains

“high”(5V) during normal operation. But, when Vcc

drops to 3.4V-3.7V, reset port becomes “low”.
