RESET FUNCTION
System reset is performed by applying “L” level to RESET pin
for 1 machine cycle or more when the following condition is
satisfied;
the value of supply voltage is the minimum value or more of
the recommended operating conditions.
Then when “H” level is applied to RESET pin, software starts
from address 0 in page 0.
Keep the value of supply voltage the minimum value or more
of the recommended operating conditions.
