EXPLATION FOR MICOM CIRCUIT
1-2. Oscillation
circuit
Oscillation circuit is a circuit with the purpose of generating
basic time for clock occurrence for synchronization and time
calculation
in relation with information
transmission/reception of inside elements of ICl (MICOM). The OSCt must always
use rated parts since if SPEC is changed, time calculated
at the ICl may be changed or no operation
is done.

1-3. Reset circuit
The reset circuit is circuit allowing various parts such as RAM inside of MICOM (ICl) to initial_e
and the whole of function to
start from the initial status, when initial power is input or when power is applied again to MICOM by a spontaneous
power
failure. 'LOW' voltage is applied to the reset terminal of MICOM in the beginning of power supply for a constant time (10ms).
Reset terminal during general operation is 5V (No MICOM operates in failure of RESET IC).
