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.

Note: The number of clock cycles depends on the internal state of
the microcomputer when reset is performed.
