Then the RESET pin is returned to an “H” level (the power source voltage should be between 4.0 V and 5.5 V), reset is released. Internal operation begin until after 8 to 13 XIN clock cycles are completed. After the reset is completed, the pro- gram starts from the address contained in address FFFD16 (high- order byte) and address FFFC16 (low-order byte). Make sure that the reset input voltage is less than 0.6 V for VCC of 3.0 V (Extended operating temperature version : the reset input voltage is less than 0.8 V for VCC of 4.0 V).
