12-4) EEPROM DETECTION CIRCUIT
●
A semiconductor memory EEPROM stores data
remembering previous settings regardless of
power-off, which are indispensable especially in
power fluctuating areas. Also, EEPROM sets and
uses other options in principle.

CIRCUIT DESCRIPTION
12-2) OSCILLATION CIRCUIT
●
It is an Oscillation Circuit for synchronism clock generation and time calculation on the information sending &
receiving of the MICOM internal logic elements and when specifications for Resonator change, the timing
system of MICOM changes resulting in errors. (Rated parts must be used)

12-3) RESET CIRCUIT
●
RESET Circuit allows the whole program to go back
to the initial setting by initializing parts such as the
RAM in MICOM with the power supply into MICOM or
with an instant power failure.
Upon the power supply, the reset terminal voltage
becomes "LOW" for tens of second compared to Vcc
voltage(DC 5V) at MICOM, and it maintains
"HIGH"(Vcc Voltage) during normal operation.
But, when Vcc drops down to 3.4~3.7V, the reset
terminal voltage becomes "LOW".
