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.
