7-2-2 OSCILLATION CIRCUIT
This circuit is to generate the base clock for calculating time and the synchro clock for transmitting data from and to the
inside logic elements of the IC1(MICOM). Be sure to use the authentic parts since the calculating time by the IC1 may be
changed or it will not work if the OSC1 SPEC is changed.
7-2-3 RESET CIRCUIT
The RESET circuit is for allowing 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 operation, 5V is applied to the RESET terminal. (If a trouble occurs in the RESET IC, the MICOM will not
work.)
