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.

(1) Power-on reset
Reset can be automatically performed at power on (power-
on reset) by the built-in power-on reset circuit. When the built-
in power-on reset circuit is used, the time for the supply voltage
to reach the minimum operating voltage must be set to 100
s or less. If the rising time exceeds 100 s, connect a
capacitor between the RESET pin and VSS at the shortest
distance, and input “L” level to RESET pin until the value of
supply voltage reaches the minimum operating voltage.
