RESET CIRCUIT

The RESET circuit allows all the functions to start at the initial conditions by
initializing various parts, including the RAM inside the MICOM (IC1) when the
power is initially supplied or the power supply to the MICOM is restored after a
momentary power failure. For the initial 10ms of power supply, LOW voltage is
applied to the MICOM RESET terminal. During a normal reset, 5V is applied to
the RESET terminal. (If a malfunction occurs in the RESET IC, the MICOM will
not operate.)
